I would love to go but I have plans in Denver on Sat. Sunday the 14th would be Ok for me.
It looks like a lot of different days people can go. You go ahead and plan it with the most available.
Don't forget Saturday the 20th. There is a car show in Parker I would like to attend, maybe a drive early north of Denver and stop by there for a free barbeque in the afternoon and check out the cars, it is all free.
