Car Event in Denver area Memorial Day weekend?

I will be in Denver from Thursday the 26th through Memorial Day weekend, leaving the 2nd of June. Any fun car events happening over that time period? I have meetings on Thursday and Friday, but will just be dealing with rental house issues (new tenants moving in) at various points over the holiday- need some car things to do!

Actually, I will be at PPIR for most of the day on Friday, if anybody from the club is going to be there. It would be fun to see some faces.
