WR, would you stand a better chance of making a group ride at a different time? If so, when might that be? Maybe no way to accomodate everybody in one shot, but if you don`t manage to hook up with any group, remember that I`m always thrilled to put on my tour guide hat.
My time up to early summer is flexible with some advance notice. I mention the weekend of May 14-16 for the possibility of coordinating a ride with Uberkul's group. So yes, if that doesn't work out another time will.
I had never heard of Iveson, but Googled it up. Yes, that`s a great location for any Black Rock/High Rock explorations. It would be easy access, either on or right after the paved portion of 34. Another option would be the Yella Dog Ranch, slightly closer to you and about the same distance from Cedarville CA as Iveson is from Gerlach. Yella Dog would be just as good for "upcountry" riding, but Iveson is definitely closer to the big playa. You migth contact both and see if you like the vibes from one or the other better. Soldier Meadows also offers camping spots for relatively cheap, but it`s almost 60 miles from Gerlach, mostly unpaved. Don`t get much prettier than SM, though. EDIT: there is also the motel in Gerlach- inexpensive, mixed reviews as to its comfort and housekeeping though I thought it was okay the one time I stayed there.
I located Old Yella Dog Ranch, adjacent to the ghost town Vya. It's a shorter drive but I think the Iveson Ranch has more potential to meet Uberkul's group. I won't need a motel since I'll be in the RV, but I do need to prepare for camping with only what I can carry on the bike. As you know, my wife rides along as passenger a lot, on-road and off, so without her I should be able to carry everything needed plus the kitchen sink.
But really, yes I'll have to put some thought into that.
It sounds like you are looking for a place somewhat secure? If you want to just park and go, most of that area is BLM, though some parts are a weird pseudo wilderness designation with their own limitations on how many people can camp where. A lot of people do base camp for free on public land, but I think probably better idea with a big bunch of vehicles so it isn`t obvious whether or not anybody is in the campsite. Or carry it all with you, of course.
I spoke with Sylvia at the Iveson Ranch, who says parking at their place while off riding is completely safe, $35 per night whether I'm there or not.
I'll pay that once to give the place a try and for the security in an area I'm not familiar with. They've got plenty of water and cooking facilities for overnighters.
