Oh my god, want to do this:
http://community.livejournal.com/bikepirates/3169462.html Dunbarton Castle to St. Andrews, Scotland. Overnight, in the kind of changeling endless twilight for which I am feeling a little nostalgic. No support crew. (I was struck by how weird the amount of support on Reach the Beach felt, though it was really nice when my knee started giving out.)
Not so nostalgic for the mosquitoes, but this is, as they say, why the gods invented bug suits and DEET.
