Great ride report.
To be honest I have anxieties about riding with a group especially since I am adamant about RYOR, safety, not holding up the pack since I am a novice, etc. I have a buddy who rides with a group in North AL. Supposedly they are known for riding the interstate with the speedo showing 3 figures all the time with every rider running beside someone.
That really isn't a ride for me.
This group looks to have a plan that would actually allow me to ride with them at some point. Have you got a link for the group you can post here?
BTW, I am getting just over 42 mpg. That 75 mpg is tempting! I am still looking for my dream bike which is listed in my profile, however. :)
