I have to chime in on Sturgis.
I believe this is THE premier rally of/for America.
It has never been about HD's only, it got started from an Indian dealer Pappy, Rally and Races, all makes of bikes, dirt bobbed for competition, Indians for the Gypsy Tour, All the fun roads, Needles Hwy, Iron Mountain Rd. and out to Wyoming, for a spacy rock. South Dakota built all of this for tourists, not just Bikers, with a capital B.
I think BARF renting a house for the month, giving extended time frame for scheduling vacation time for the rally goers, might be doable for a greater number of riders. With maybe 12 days of official rally, the roads don't close, other rallies, Corvettes, Mustangs, John Deere, Deadwood Nites, are rolling thru the summer
My grandparents came from Taft, schedule in some wildflowers blooming, I should make this one, , ,
Nate, My '07 trip to Sturgis, I found a brand new red '08 Hyper chained to a dumpster in an alley in Sturgis, my lust for something in a red dress, got started there.
