Anybody have input on what it would be like in an atv? (assuming the weather was reasonable) 90" L x 52" W (with my tires), Clearance 10.25". Good idea, bad idea?

The ATV version of the Wells book doesn't list Elephant Hill...made me think maybe it's not adviseable?

This website has many pics along the trail....
