i'm only in SD for the Sunday , Monday , Tuesday before Inzane so I'm trying to fit just a couple of things in out of the 100's to due plus i will be riding with just my other half and never have been in that part of the country before and don't know what to expect as far as HEAT and things like that so i really don't know how far i can travel between places.
I'm hoping to due alot of riding with fellow Valkers at Inzane.I'll also be their a few days after Inzane so if anybody is still around lets get together and ride.
Sorry, cant help ya on anything that far south.
Expect-Storms, sun, wind, pheasant, deer/ antelope, and more wind.
As far as the heat goes in SD its not bad. Its not as humid as it is here east of the Missip. In the plains we have had temps from 75-100 deg. The heat never wore me down as much as the winds did. I stay off I-90 anymore. Just bring chap stick and sun block. Long sleeves are good to. Once in awhile we will wear a bandanna over our face to help with the heat. Wear something on your head. I wear a cheap visor like they wear in golf. Doesn't have the wind lift like a full hat does. I'll also wear a bandana under it since I'm shy of hair up top. If you wear a helmet then I'm not sure what to say. I roasted in my 3/4 in 06. Never again. For you or the Misses, soak a bandana in some cold cooler water and wrap it around your neck. Yes, I carry a crap load of bandanas!

Someone will let ya use there cooler water along the way.
I never been hot in the Hills. Cold, but never hot. You should be good there.
We have done anywhere from 500-700 mile days in the IA, NE, SD heat with no prob. You never know, you might like it so much you won't make IZ! See ya at the B/G ride!
