I don't have much time on Sunday (going to the football game) so how about something shorter? Would a flat 30 at 7am still hold your attention?
For your viewing pleasure, I've modified the route map. I must admit, some of this I'm not personally familiar with so I'll try to scout it between now and Sunday, but I want to get something approximate on the wire so we can lock in the ride, if it works this way. It starts at Folley Park, Ray Road just east of Val Vista Rd. Val Vista becomes the southbound route, then Hunt Hwy and Alma School Road, over to Pecos Rd and back towards the start. There's a canal path right there also.
Opinions please? As before, I'm sure somebody knows some better side-streets or low-traffic alternatives, but for a simple little 7am Sunday ride this seems pretty casual.
