Heck no I didn't. In 50/60 zones I slow down to something a lot more reasonable. I know of one spot marked 50 that I get a bit... frisky on, but it was AFTER i'd passed the reason for it (a school). Grew up around there, so I know what to look for, it's just that corner signed.
Other than that, in low speed/high population zones, I'm pretty dang careful. Anyone that rides with me regularly can tell you that.
