Thanks for the advice!

http://www.pedfriendly.org/ped_safety.html turned out to have my answer; I can ride on the sidewalk, but am not obligated to do so, as long as I'm not basically in an area with a lot of foot traffic. Many thanks to people for pointing out "hey check the local regulations!"

very weird song associations

Okay, so why does the combination of autumn/Queen make me want to run or play the Against the Giants modules? I mean, I own them, and they are pretty quintessentially old-skool AD&D, but I've never actually played or run any of those scenarios. And why those modules in particular rather than any other classics? It's not like I'm sitting here going "It's a Kind of Magic is totally the theme tune for The Lost Caverns of Tsojcanth."

Weird.
