I have been going to the '49er for many years. It's a great rally, and returning to Mariposa will be even better.
When I first starting riding in the early 80s the rally was held in Mariposa and I recall getting up early on Sunday so we could all ride into Yosemite for the Sunday Brunch at the Ahwanee hotel.
Unfortunately, I'm going to miss it this year, as I will be volunteering at the BMW RA tent at the World SuperBike races in Tooele, UT.
Have a great time there Melena! I will be thinking of being there.
