I need some positive TE energy for this one:

I registered to ride the second day of RAGBRAI, and now I'm wondering what I was thinking.

I have family in the area who will transport me to/from the ride, and I am sure they will hook me up with other riders, but I still have no idea what to really expect.

The more I read on the RAGBRAI message board, the more unprepared I feel. My longest ride so far was 50 miles (once... supported... with friends). It all seems so intimidating now. I have 3 weeks to get mentally squared away (and figure out what to pack).

Any advice would be really helpful....
