Anybody got a lair?

I was just wondering, does anyone know of a place that they hang out at or go to once in a while which you think of as your own TMNT sewer lair?

Sounds a little crazy?

Well, a few years back my friends and I stumbled upon an abandoned underground garage. We went in it one day and found three sub-levels! the first sub-level (the top one) has a large grait at the top and a few other smaller graits around that let light into the place. There is a ramp that goes from the first sub-level to the second sub-level (we go down that thing with anything that has wheels!). There is two stair ways to get through the sub-levels. The third sub-level (the one at the bottom) is full of corridors and rooms; plus it's pitch black down there! We investigated the place and did some research; and we found out that there was supposed to be a residential building built on top of the proporty in the late 1970s but the project got abandoned with only the garage built.
20 years later we find the place and claim it for our selves (secretivly ofcourse )! This summer, one of my friends is going to dive into the powerbox and try to get the electricity working (though this may cause problems).

If anyone has an interesting "lair", tell us about it!
