I've actually played more this summer than I have in recent memory, thanks to my girlfriend and oldest son getting into it. Still only managed to break 80 once. I miss high school, no wait I really don't.
I just built myself a whiteboard. It is slightly elevated off the ground by a couple long legs made from something similar but smaller than a 2x4 flipped tall side vertical.
It does seem to make a difference vs the top of my black impreza.
Next step will be to get some powered refrigeration under that baby just like an ice rink lol
