For the road trip enroute to the event, I'd certainly be carrying. At the event itself? A bit of finesse & planning might be a good idea. If I decide to attend something like Sturgis, I always try to do it with a group of known friends. There is more security in numbers, more eyes on your side, and a group of friends that are of a similar mindset are less likely to be targeted, or singled out for some kind of negative attention. There are no guarantees of course, just a risk reduction if you number more than one alone.
It's a hard call to make. We all know that carrying a firearm limits your lifestyle, & how you socialize. The more your out there, the better the chance that you might have to use it, which will change your life forever. So it's a risk vs reward judgement.
My own personal lifestyle would be totally unacceptable to most people under 40. I generally avoid crowds, fairs, concerts, etc... The only exceptions I usually make are shooting ranges & shooting events where everyone is armed, & of a similar purpose. But what works for me, obviously is not "The Norm".
Best of luck to you though, really hope you have a nice, uneventful visit to Sturgis.
