I ride my road bike on gravel, just very carefully.

Breaking traffic laws is never a good idea. Drives me nuts when the kids around here ride the wrong way in the bike lane. It forces me to go out into the traffic lane on my commute.

Of course on rainy days, I've been known to ride the wrong way myself, on the sidewalk. There is almost no foot traffic and I ride slowly, yielding to anyone I happen to see. (One guy with a dog I think.) It keeps me from having to cross a fairly busy road twice in less than a tenth of a mile. When it's not raining, I take a longer route home.
