I followed your earlier link to Race Dezert and joined. I hope to learn a lot from that crowd.Here's some info on that El Paso race:
Looks like it's scheduled for March 28-29 of this year. Also have something scheduled for July 4th weekend, but it doesn't say exactly where.
I've also seen on the Mexican racers' forum events near Juarez. If I come across any info, I'll post it up here.
Thanks a lot for that. I have a lot of reading to do and questions to ask.
