+100 on submitting problem reports. I've submitted four now, I think. Three are already resolved. The other they're working on. FWIW, I assume it helps to substantiate your claim when you submit an report. I try to link to a city or county website/blog, online PDF map, or other resource when possible to show that I'm not just making the stuff up, and I hope that it helped to validate my report and speed correction.
I do appreciate their responsiveness, though. They're going a great job w/ this thing. I still use Ride the City a lot, too. Another gvery valuable mapping resource for cycling if it covers your area.
