I run there every year, is that with MORPCA? I am trying to decide over that event or the Viper Club one in May.
I have been to VIR a few times, differences being well, the BIGGEST is Mid OH is a very technical track, shorter than VIR, lots of camber changes and lots of spectator seating to run into

As much as I loved VIR when I lived closer to it, now that I am by MO I have to say it's the most challenging track I have ever been to, and it will definitely keep you on your toes! I ran MO last wknd with another PCA group and the track is in excellent condition, May will be the perfect month to go.
