Thanks again everyone for your comments. The above was especially helpful. I did my first "event" over the weekend, and could easily see that what you all said was very true. Really, not much reason for concern, but it's still good to use common sense.
I never would have thought about the need to remember where I parked my bike - until I saw all those bikes in the racks. Wow, harder than finding your car in the mall the days before Christmas. And this was no where near as big as the LiveStrong event.
I did feel pretty secure during the rest stops, but the dinner at the end of the event was a different matter. Not as many bikes around, non event folks were close by, just a different vibe. So I used the gloves in the spokes and helmet on the wheel/tube. My husband thought I was crazy, but I felt more secure.
Thanks again,
Dawn
