I have a friend with a hall/barn type of thing who allows me to do it there. It's fun. He smokes joints and talks about all his cars while I do my thing. I learned not to let him touch my car or explain things to me right after he smoked one.
But I have a tougher problem right now - CO emissions are too high. Need more than a barn.
Nice. I wish I had a space to do that kind of thing. I don't think I'd feel comfortable doing much more than changing a tire while parked on a semi-busy street
