I'm planning to go in a couple of years. My kids are too young for me to be away for so long right now. Like Bill said its close to 1,800 miles away from me. 2-3 days there, gotta stay at least 5 days then 2-3 days back...
Hopefully in a couple of years when they don't need daddy around as much, I'll go.
If I could could go for 5 days maybe 6 I'd go. I want my bike though, no rental.
You don't need 5 days in Sturgis. I rode out in '06. 3 nights was plenty for me. Probably could have been 2 nights and still had a BLAST. Besides, too many people want to try and see/do everything when they go. Just pick a couple of things and really spend time doing them. You can always go back.
