One of my favorites on PBS, "Great Old Amusement parks" is coming on in about a week. I always enjoy documentaries by Rick Sebak from WQED in Pittsburgh; he also did "A Hot Dog program"
Also the Travel Channel is bringing back some older programs including "Top 10 Coasters". So if you haven't seen the newer ones on Las Vegas, waterparks, and the state fair, make sure you don't miss it.
