Avoid Deadwood, SD during Sturgis?
Any advice on whether I should avoid Deadwood during the Sturgis Rally? I'd like to spend a few hours there when I pass through the area, but I didn't realize it was Rally Time. To (possibly) make it worse, the only time I can spare is Friday (8/10) late afternoon into the evening, so there's the after work and weekender crowd, too. I can't change my schedule, all I can do is go this Friday or skip it.
I'm sure it will be crowded, and I'm ok with that, but I just want to be sure it's not awful, like "3 hours to find a parking space and walk a few miles" awful.
