Generator security at Nascar event

First time camping at a Nascar event is coming up. Staying at private campground(big field) right outside the track. High temps will be in the 90s so Im borrowing a generator from a friend to be able to have some air conditioning. Its a big generator, will take 2 people to pick up. I plan to chain or cable it to the bumper. Is that usually all the more security thats needed? Or should I lock it up in my suv while attending the race? I know that if someone wants it they will get it, weather chained up or in a vehicle. Just dont know if generator theft is a big problem. Thanks
