Two events, which have nothing in common, though they share a name.
White Rose Thunder in York, PA. Went last year, will go this year as well. The flat track racing is a blast. Yes, it's distinctly Harley leaning, but it's simply a blast. This runs from Thursday to Sunday, with Saturday being the big one.

And the White Rose MC Club Hillclimb. I've not been to this specific event, but I've been to others at this club. Nice place, lots of fun. Sunday only event. I can't go :-( son has a soccer game. Which actually says something about the club. Last year I mentioned a similar conflict, and they told me in no uncertain terms, go to my sons game. Family is the priority to this club.
