I did buy a bike today, though. Spent a little more than I would have liked, but not really more than I expected. Also took the other bike in to get it fixed up (the full mountain bike, the new one is meant for roads and paved trails, it's lighter and doesn't have any suspension)... Anyway, it's going to cost about what I expected, at around $300 -- it was sitting in the sun for a couple years on my apartment balcony, and that takes quite a toll. The handlebar grips literally melted. Literally. It's still a good bike, though (frame, rims and such are in perfect shape), it cost about three times that new, and probably about a third of the $300 is labor, so it's well worth recovering.
I really meant to do this months ago before I left, but I wasn't going to use them until this summer anyway, so it really doesn't matter. I'll get a fair bit of use out of them over the next few weeks (was going to go today, but the tired has set in and it looks vaguely like it might think about raining sometime). And they ought to be better preserved in my garage than the one was on my balcony.
Really tired now. Still a week yet before I'll be mostly over the jet lag. Montreal is going to really suck... I'm pretty much going to either sleep through all the parties, or wish I had.
