Kinarfi,
Let's see since I have had the T4, I have only ridden on some small dunes in Mexicali, but I have ridden my quad, and a motorcycle all over Glamis a few years ago the north side near Highway 76. I have also ridden El Golfo which is to the southeast of me in Mexico on my quad. I need to buy a rim and a a couple of tires, and will try to get out again soon to Glamis.
It looks like I'm going to Ocotillo Wells near the Anza Borrego Desert on November 8th, so I need to buy them quick, or I will be riding the quad.
Also I would love to take part in a Trooper meeting, you guys have knowledge that I need. I kind of have 2 many thumbs, but with instuctions I can figure it out. I would be have to travel around to AZ, Ca, or Mexico for a weekend or so.
