Wow! I hope I'm still riding when I'm 62! You go girl!

Let's see...

Heavy traffic - as long as you have a lane, forget about it. (That's what I do ) Do be as brightly colored as possible. I've taken to using my taillights even during the day if traffic is heavy.

Crossing traffic - slow down before you get to the intersection so you can assess the traffic behind you. Signal your intentions. Maybe it's just that I'm lucky, but if I signal and make eye contact, drivers will often let me in. (Maybe it's the lipstick.) If neccessary get off your bike and use the crosswalk. It's a pain, but it works.

Falling when you stop - unclick before hand, so you've got that foot ready to go down.

Riding too slow - forget about it. You're riding for you! Have fun and don't worry about speed. Unless you're planning on racing. You'd probably win your age group.

The guy - he knows you're new. He likes your company. Everyone makes mistakes and does goofy things. Even accomplished riders.

Have fun and ride lots!
