My update:
I ended up wearing a canvasy type Old Navy jacket with lining in it that I found at the thrift store for $3.00 (!!!), skinny jeans, the most motorcycle chick-ish shirt I had, and slouchy black knee high boots.
There were people in all sorts of gear, some die-hard looking types in their leather chaps and vests with their long beards, others in the more expensive Kevlar looking outfits, the guy with the nicest paint/vinyl job wore khaki colored cargo pants and no-name athletic shoes, there was even a chick wearing itty bitty jean shorts with a camisole and lace racer tank over the cami and some weird type of brown boot that went up to her knee, almost like a muck boot. Someone asked where her britches were and she responded that she had chaps in case it rained. Haha
We didn't crash, my butt didn't go numb, and it was a lot of fun! My boyfriend agreed we would do it again.
The President of the organization that hosted it told us to keep tight together because last year during some places the tribute riders were spread out 10 miles long. My boyfriend guessed there were at least 200 bikes there this year, but no real county for participants that I have seen.
I'll post the few pictures I took in a second.
