hmmm...kj up carnage, i personally wouldnt unless you are ready for some winching and body damage. up the left hand side, no problem. thing is, lefthand really isnt much more than a dirt road. carnage can be tough even if you avoid all the obstacles if you are running a solid axle and 32s.
i ran carnage about every other weekend when i had the tj (on 33s). it is a fun trail but unless you get there 1st thing in the morning you will be waiting in a traffic jam. usually someone breaks (most guys use carnage to work the kinks out and to try out new mods) making the wait even longer.
a good thing about carnage is that is is short. you can always walk up it 1st to check out everyone else running it
