Texan, I had it pretty well figured out, that's why I said "and/or location", but I thought it would be more fun to post it the way I did, just being a wize azz!
The real joke is, the first year I went I didn't even know about real reason all the bikers were in Sturgis, I thought they were there to watch us race! And even after that it took me 4 or 5 years before I went downtown to check everything out, if it wasn't a race bike I could have cared less.
If I remember correctly, it was shootings & fights that was the spark that created the Buffalo Chip & places like it, the crazy bikers needed a place to stay & Sturgis didn't want them 24 yrs a day all rally long.
