Urban Exploration... Did you go Inside?
I explore abandoned places, most often farm houses here in Ontario. I post my photos to Flickr, my account there and some of them I select to post to the groups I began for Ontario Rural Ruins and Canadian Rural Ruins. People like my photos and will often ask, "Did you go inside?".
I very seldom go inside the abandoned places I photograph. Not everyone understands this. Some people think you aren't a real explorer if you don't go inside. But, I feel differently. I love to see the outside of the homes for one thing. I also prefer the places which are very deteriorated, eroded by the elements and overgrown by plants. Those kind of places are not safe to enter. I know one explorer who has some engineering and fire fighter background, he takes more risks and enters the places which are risky. But, he is educated about it and decides to avoid anything dangerous.
There is another issue about entering an abandoned or derelict place. You don't own it. So you're trespassing in reality.
At an abandoned place you decide for yourself how far you should go. For me, I walk around the building (watching where I step) but I don't go inside. That's the point where it doesn't feel right to me.
About Trespassing
Basically, trespassing is going onto the owner's property knowing you are doing so and not having permission from the owner. So, by the law urban and rural and industrial exploring of property you don't own yourself, is trespassing.
But, I do it anyway. Sometimes I do stop at a clear sign that the property owner does not want anyone there. If I see a 'No Trespassing' sign or if the property has a locked gate blocking access, I will stop there and just use my camera's zoom feature to get what photos I can. You can take photos from a public access area - that isn't trespassing. You can walk up and down the street along a 'No Trespassing' location and take as many photos as you like. (From the public side).
But, I do sometimes take a step onto the property so I can see more. I don't cause any harm. I don't litter or take anything away with me. I also don't enter the premises (the building) on the property.
The odd times I have had someone stop and ask me what I was doing it was a neighbour who was curious. Sometimes they will tell me all they know about the building and the people who owned it (especially when it comes to old farm houses).
Once, I was asked to leave the premises by security. This was at a location in Orillia, Ontario which had once been a sanitarium. I think they left me to my own devices for awhile before approaching me. I was able to have a nice walk around and I had just finished taking the last photo I wanted to get when they stopped me. They were very nice about it and I had no problem leaving by then of course.
Just to note: a trespasser would probably not be prosecuted if the property was not fenced in, did not have trespassing signs and the land was open - if the trespasser did not interfere with the owner's use of the property and if the trespasser left without incident once (or if) they are asked to leave. (You can be asked to leave by someone who is not the owner and that counts too).
This is why I am strict about the 'Leave only footprints; take only photos' theme of exploration. This is also why I almost never enter the building on the property but I will carefully walk around it to view as much of it as I can.
Some people may think the property owner is just being a miser, a Scrooge or a Grinch about the whole trespassing thing. So, you need to consider it from their angle. First, if you are injured while on their property (even uninvited or as a trespasser) the property owner is liable for whatever happens to you. Not quite fair is it? The property owner isn't even there to have a voice in your exploration, yet they are responsible for you while you are there.
Of course, any harm you do while there will be left for them to deal with or clean up. So don't leave so much as a coffee cup around and don't take anything you didn't arrive with on your person. A property owner can claim ownership of the photos you have taken while accessing the property, if you were not on public grounds while taking the photograph.
