I think youre right west tx , and yeah Im not saying its gotta be the Baja , but 10 -15 bikes on a 20 mile course might be in order.  I dont know honestly if its an issue at all to host something like that on county land , I suppose it shouldnt be a problem.  If you PM me West TX  Ill give you my address for google earth and you can check out the birds eye behind my house , Id say its 10-15 miles as the crow flys to the Mountains and Query that youre talking about.  The best riding is definitely up at the base of those mountains.  I think it may be a thing were Id have to get it all put together and course mapped out , then try and get the guys from AZ to come over, but really I think if someone is within 400 miles we could make the drive worth it. And yes a ride out to Fabens would be fun absolutely , the one thing I like about the far east side is the communities seem to be pretty atv friendly , just about everyday there a group of riders at the gas station there in horizon who rode there to get gas and the law leaves them be.  I think we might be on to something here man.  Shoot Ill break out the smoker and BBQ too to boot.
