Actually, Sturgis the town is boring (to me). We stayed in Deadwood.
Not much on joining the lemming type rides to here or there for some damn reason - Devil's Tower, panty's free Wednesday, etc.
I am with you on both points...We have stayed at the Super 8 in Deadwood for about 15 years... I wouldn't say Sturgis boring - it just isn't worth the hassle of the traffic and is full of wannabee's in brand new everything... We might get into Sturgis once each year just to cruise the vendors...
And we go out of our way to avoid the lemming rides...even after 15 years we can always find a ride or route we have never taken before...we have been going futher into Wyoming or further south each year looking for open roads and new sites...
