"I'm always most afraid of young kids learning to ride and dogs on extra-long leashes."

I've had no problem with dogs (so far)

Kids can be the worst on bike trails; you say "on your left" they GO left...right into you.

Ok, so now I'll say a friendly "hi, good morning" kid is startled and plows right towards me.

Next one heading towards you they look right at you and kareen into you. It's a coordination thing they don't have yet.

Turn a sharp corner at 15 mph and there's Mommy and Daddy with 2.5 kids and "look at the ducky!" and all 4.5 bikes are strewn across the trail.

The worst is right after Christmas they're all out there wobbling with the new bike that doesn't fit....

I love it that they are bike riding, that part is great but you never know what they will do and you have to assume the worst. So I gear down and concentrate on my spin because it's rare I'll get up a good head of steam.

I love my local bike trails, favorites are on the Bay Trail, so scenic but I'll take cars anyday over rollerblades and kids
