hhhmmm i ride with 8 younger kids from s.i. every weekend. they come out here to ride 63 and 80 off the gsp. i heard of 102 and its closes to me but i hear you get bothered every few weeks? i would like more info on 74, i would think its the same trails as 63 and 80? it all comes down to the parking of trucks ,etc to stay invisisble to the local p.d. :thumbsup:
