I'll probably do Bonham. Which is better, the 65 or 54 mile course?
I'd do the 65. I'm not sure if the 54 route includes the Leonard Leviathans (small rollers we call hills here).
I'm a little surprised at the paucity of weekday rides. Here in Atlanta there are at least a half dozen rides any day of the week (except Friday, for some reason

). I'll try to get up to Plano at least once.
The PBA is a Plano club...a suburb of Dallas. There is also the GDB (Greater Dallas Bicyclists) that have their rides, there are clubs in Arlington, FortWorth, Frisco etc. I would say we probably have the same amount of rides in the area if you count up all the clubs. I don't belong to any of the other clubs so I can't speak for their rides.
Just on this side of the metro, we cyclists are such a pain in the ass that a couple of local redneck-villes are trying to figure out how to ban the hundreds of cyclists that roll their streets several days a week.
