"You don't want to do Webster Pass. It is so narrow that at one point you have the drivers wheel about a foot up the mtn from the road and the passenger tire is on the outside edge off the road with at least 5-600' of vehicle rolling if you run off. I did it once and will not do it again. OBTW I am not generally concerned on shelf roads. Have done many that scared the bjesus out of others with me."
I am going to respectfully disagree about Webster - I think its a pretty easy drive and for a small YJ jeep it won't feel that narrow. But, yes, it is a narrow shelf road, and that can be intimidating and or an issue as a small driver error or just loosing focus for a minute has big consequences. I'd say Kingston is actually a slightly more challenging trail to drive than Webster due to the road surface, but there is some 'eye of the beholder' to that as well.
There are so many great, relative easy to moderate trails in the area - a few suggestions:
Bill Moore
Jones Pass (probably one of the easiest)
Argentine/McClelland
even our own Devils Canyon (also quite easy)
