Anyway, I left the house around 1, wandered through Art Beat for a bit and then struck out for the western 'burbs via the bike path to Alewife, and then a very nifty little unpaved path from there to Belmont, and from there on local roads: Blanchard -> Concord -> Clark -> Thomas -> Beech (somewhere along Beech there was a really nice little shop with tasty gelato) -> Burnham -> Sycamore -> Belmont -> Beaver -> Lexington -> Bacon.
All told, my rough measure off the map gives it as just over 8.5 miles, which isn't too shabby, and about 4 hours. I did bring enough water, but I could have used more sunscreen. Happily, I brought a sunhat, at least.
I felt pretty wiped out when I got there, but sitting in the a/c and drinking more water perked me up, and then I gave myself a short shower with the hose (note to self: next time, bring a change of clothes) and now it's 12:30AM, and I'm still awake! But not for long...
The party was nice, almost all people I didn't know, but who were fun to meet and chat with. And one of the other guests was kind enough to give me a ride home, so I didn't have to retrace my steps in the dark! :)
