Nice to see someone else shooting film at LRP. I was up there shooting with my Canon P for the Vintage Festival over Labor Day - I saw another guy using an M3 with Summicron that day as well. I was focusing on primarily detail shots rather than on-track action this time (I have a lot of track shots from years past). I've never taken my Rolleiflex up there, but I probably should - I think there's a VSCCA in a couple weekends.
Look forward to seeing the photos. Here's a couple of mine from the Vintage Fest (hope you don't mind; I'll happily remove them if you prefer - just let me know).
