+1 on the lone wolf philosophy. Not really trying to be anti-social, but I am familiar with too many scenarios where diverse riding abilities caused accidents and injuries, not to mention the testosterone factor when you get a bunch of guys together who end up trying to show off to one another or out do another...having been involved in that and being lucky enough to survive without injury, I learned that lesson and ride at my own pace, on my own schedule.
Downside is if you go down in a desolate area, there is no one to help or if you have a mechanical break-down there is no one to assist or give you the benefit of their mechanical knowledge and abilities.
But have been doing the solo riding scene across this country since 1978 and will probably continue to do so.
Am in the early planning stages of a two week ride next June from Dallas-Fort Worth to Pismo Beach, Morro Bay, San Simeon, Carmel, Monterey, San Francisco, Yosemite, Lake Tahoe, highway one, Crater Lake, Columbia river gorge, Seattle, Vancouver, Banff, Glacier National Park and back to DFW.
I know this might be overly ambitious and will very likely have to shorten that list, but does anyone have any personal experience on really good twisty and scenic roads to and from those areas, good restaurants and hotels or B & B's to stay at?
