Heat , NHRA tech.
I have been to the BPG Nats every year it's been at Columbus . This year wasn't bad but some of them have been HOT !
My car passes tech but it is not cheap to keep the cage certified , renew NHRA license/membership and buy new belts every two years when this is probably the only place I will run my car that will require all of that . Doesn't keep me from coming but I know some out there who just stay home.
