Buying Nothing is good for meeting the neighbours. A lot of the ppl on my street have been here, well, forever. The houses were built in 1970, and many original owners are still here. They're all super nice profs at the university or retired profs, and do they have some nice gardens :-) Teachers tend to have nice gardens I find, they have time off in the spring/summer to do the work necessary.
I'm getting tomato seedlings from one neighbour and chives and oregano and thyme from another. Woohoo!
