Unless the forecast improves drastically I'm out too. It's raining here now, supposed to rain all night, 70% in the morning and only improve to a 50% chance of thunderstorms by mid afternoon tomorrow.
At MIS last year I mounted it on the left scoop. Used double sided tape to hold the gopro mount there. Sometimes I use the suction cup mount and put it on the water pump cover on the right side.
Here's one with it mounted on the water pump cover...

This is us at MIS last year...
First lap or so is to let the pace car get at least a half track ahead. We don't really pour it on until end of lap 2 and then 3.
