I love the Legends idea at NHIS, because he'll get the experience of the racing, without the crushing crowds, and without the deafening noise.
I'm concerned that the noise at Lee would be more than he'd be comfortable with. It's loud enough to be heard a few miles away at the dragstrip on a hot summer's night.
There is also a small dirt track up in Canaan, which has stock car racing on Friday nights in the summer. The venue is the right size, but again the noise might be a bit more than he'd be comfortable with. It's also a bit of a drive, so that might add another issue to the mix as well.
I'll see if I can come up with any other ideas.
