When we went, we got there the Wed before the event and were glad we did. Nobody there, you could pick and choose. We rode all the scenic loops, checked out the campgrounds. Ended up at Happy Holiday RV Resort 5 miles outside Rapid City. Clean, FHUs, quiet at night and far enough outside the city that the stars were great.
The Chip and the others like them have burnout pits and too many hard partiers. I'm no Bible school teacher but I like my sleep. Anywhere around Sturgis is crowded and noisy. In Rapid City there are grocery stores, Walmart, restaurants and the cg was quiet at night.
I'll also say that the roads and parking lots are so jammed during the event that you could hardly park. All the wonderful rides and scenic loops that were so awesome the week before were no fun after the event started. We actually left early like Thursday because we had had enough.
We live 45 minutes from Daytona so have seen plenty of Bike Week action over the years. Whats great about Sturgis is the scenery and roads.
The hill climb event was cool too.
