I've just spent a good 2 hours modifying and adding bike routes around my house.
Just thought I'd spread the word. Hopefully my edits will assist when I'm planning my routes.

I did a bunch of edits on local bike trails and bike-friendly roads. They got rejected with "I looked at the satellite view and don't see them." So I had to go back to each one and tell them "Look at the street view at address such-and-such, and you'll see the bike route/etc signs..."

I hope your reviewers aren't such morons. ;-)

I haven't had that yet, but a couple of trails I posted we're pretty remote. You can't see them from street view, but they're clear as day on satellite. I'm hoping they approve 2 important ones for me. As of now when I plan a route it has me going down a freeway or a good 5 miles out of my way when I try to plan them.
