Wow, it mapped out my route fairly well until it got to Tampa, where it had me ride up Westshore Blvd, which is a horrible road for a bike. It is five miles of narrow road with no shoulders, no lights, and bumper to bumper cars using it as a major commuter line from South Tampa to the Westshore business district. I go only 2 blocks on this road then take a residential street a half mile East, then go North on a very nice four lane road with a bike lane for the first mile or so. I think I will try using the link they put out there to report inappropriate bike routes. I will suggest the route I take and see what they do.
One other point though: there is a half mile MUP on my route through St Pete, and it used it. Very nice.
