I just returned from 4 days at Hershey and had a great time. I scored some wonderful NOS parts for my 1935 Ford truck at very reasonable prices, talked to a bunch of friends, made a few new ones, and enjoyed rain-free and sunny days.
The down side is that the vendor stalls are about half full. It's just a sign of the times, but still is sad to see. I expect that Hershey will continue shrinking and I hope AACA manages the process a bit better than just letting people purchase spaces and either not use them or just park their cars.
If you have never been, it's still an amazing experience even with it being "thinner" than in the past. Time marches on!
