There's a Harley week, a sportbike week, and black bike week.
I wouldn't go on Harley week. Doubt you'de have any problems, but it will be over run with harley bikers, and alot of the kind who hate sportbikes.
Any sportbike week is fine, including black bike week.
I'm white, but have been to black bike week several times(without a bike), everyone is always cool.
Most of the big gatherings are at South Mrytle(where black bike week originated, from stupid segregation of decades ago), but it extends all the way to North Myrtle.
It's usually the week before/after Memorial day.
