My vintage racing group SOVREN is running at Portland this weekend, in conjunction with the British Field meet. Between both groups their should be over 400 vintage cars. Their honored marque is the Austin Healey. We run Sat, Sun, Monday (although I am leaving Sun night so my daughter can have a day to get ready for back to school).
There is a CanAm group running which promises to be awesome. Look on http://www.sovren.org for the poster and the details
If you come out, drop by my trailer and say Hi; I am the orange 911 #901. No 914s with me this weekend, just the F-250.
