well the legality is the gray area. there aren't any obvious "no trespassing" signs. but i'm sure it's someone's property. i guess it just comes down to if this someone knows we're there and if he/she really wants us gone. i honestly think we'll be okay. it's such a cruddy, dilapidated place....if anything at all happens, it would probably be some cops or land owner telling is it's not safe and that we shouldn't be there
but that gray area of the legality of it is partly what makes it so much fun! i'm going somewhere other people don't or maybe can't to get some unique photos.
If you check my flickr links out i have been in quite a few cool place, and by doing so was "trespassing".

Ive been into a shutdown Car Factory and Production Line... actually been in there about 30 times cause i live next door.
My most recent event was going into a Ford Cars, Foundry that had closed down. After having 2 successful trips round, i had a friend who wanted to go, so off we went 9pm on a sunday night. There was security on site there always was, and not a small fence to jump to get in. We must have been in there 10mins and we spotted a patrol... after he moved off we thought, he couldnt possibly be looking for us. But we made our way onto the gangway, and we could see about 5 or 6 gaurds dotted about, speaking quitely into radios.
Erm.. BUGGER!
We were then approached by a security gaurd that lead us down to an awaiting squad car... they took our names and details and let us off with a caution.
My advice, dont get caught.... if you do, dont be a knob respect your in the wrong and whatever you do, do not steal anything from these places or cause any vandalism what so ever.
When the policeman asked what was in my camera bag, i gladly showed him, I had alot of camera gear, some dust face masks, a old pair of safety specs, 3 tourches, one is actually force issue.. so he liked that

, so as soon as he saw that he pretty much knew i wasnt as stupid as i first seemed. But if there had been a couple of screwdrivers or a crowbar.. or some stuff from the place your in a night in a cell would have been on the cards.
Houses and things are a little different, your more inclined to bumb into other explorers or bums

. Scaryist moment of my life was at the old RAF site, again on my flickr... opened a door into a pitch black room, flicked the torch on high and a **** load of pigeons went spark crazy... lol, i crapped myself.
