^ I recommend wearing water resistant footwear - it was nice today, but supposed to rain again tonght. Walking through long grass is pretty much a guaranteed if you're gonna be walking around the course (I hate walking in damp socks). Wouldn't hurt to bring a couple of umbrella's - you can always leave'em in the car if it's nice, but yesterday the rain was off and on.
Also: bring water - and enjoy!
If you're looking for decent food while you're here with the Mrs., check out:
Milford House (5.5 miles from the Toboggan course), or
Baker's of Milford (literally right across the street from the north entrance of the park) for food + some classic cars (people show their cars every Sunday).
