Gates open at noon, cost is $25 for test & tune runs. Helmets are required no matter how slow your car is.
Lapeer isn't the greatest track, but it's not too bad either. And even if it's "busy" you'll still be able to make pretty much as many runs as you want

As long as the weather cooperates it should be a great time. I'll be there with at least my 91 SHO plus (possibly the 93 as well), where I'll be showing everyone how to run 14's for less than $1000
