I took a trip 4 years ago to Monterey and back...and on the way back it rained down the 101 from Monterey to Ventura (280 mi). $20 rain suit from Target under my leathers (water proofed with mink oil) kept me water tight.
If Grand Canyon is too much for some, we can stay more local and visit perhaps Granite Dells, Watson Lake, etc.
I'm open where to meet in the afternoon...maybe on Wiskey Row somewhere? Count me in.
