Abandoned places are demolished before you make time to visit them. So, make sure, when you do get there, you have your camera ready. You may not get another chance.
My first time as an urban explorer was not with this camera. So far, the Panasonic has been my favourite camera and the second of four which I have bought.
Photographs of the First House I Explored (now Demolished)

The first house I ever visited as an urban explorer. This is how it looked from the gate at the bottom of the driveway, just off the main road.

This was the front door. Lovely arch over it.

This was the left side of the house. Later I found photos of the inside and realize that was a stairway where the windows go up on the side.

This was farther to the back of the house. Likely the wooden addition was a summer kitchen.

This is closer up looking at the front of the house. I like the gingerbread trim and brickwork. The colours were great.
My First Digital Camera on my First Urban Exploration Adventure
The first camera I bought for urban exploring was made in China by a company I have not heard of before or since then. I bought that first camera at Zellers, a Canadian department store which I was working for at the time. I was so happy and proud to have my first digital camera. It was liberating to be free of film and film developing which made photography so expensive as a hobby.
That first camera needed two double A batteries. I brought extra batteries with me. But, the first time I used the camera the one thing I did not know what how important it is to have a memory card. I had none, just the memory which came with the camera itself.
So my first urban exploration adventure was not as long as I would have liked. I ran out of camera memory before I had taken even 20 photos. That may seem like plenty. But, when you are photographing an entire house, the remains of the garden, the barn and then the more interesting parts of the house where I wanted to zoom up and see more... I was out of memory.
Urban Exploration Doesn't Come with Second Chances
I still did get photos which I treasure. Unfortunately, that was the one and only trip I made to that first house. Before I got up the nerve or found the time, the house had been demolished. As an urban explorer, two things I have learned are the importance of having a camera I can rely on (with plenty of memory and a fully charged battery) and the fact that nothing lasts forever. You don't always get a second chance.
An urban explorer needs a good camera, a reliable backpack to keep it in, and a map to both mark your place and show you the way to go home again. You should also dress appropriately, don't forget the footwear!
