I _thought_ our street was 25, but R. says it is 30. I just got passed when I was going 23 mph. The idiot who passed me did so with oncoming traffic (that they couldn't see because of a slight hill), across a double yellow line, when about 2 houses down the road they had to brake sharply to turn down into the subdivision. This gave me pause, because T. and I hang out in that subdivision. I called it into Acton traffic, and wound up leaving my sad tale of woe on someone's voicemail. I guess if it really is 30 mph, my next project would be to try to get it reduced to 25.
ETA: _with_ the plate number. Which I'll be watching for in the subdivision.
