I have the opportunity to attend some training sessions for my job. I live in Pennsylvania but can go about anywhere. I would guess that the training will be 8 hours, ending about 4 or 5 pm. Hopefully there won't be much homework. What time do most coin shows end? 9 pm? If the dates lined up, what would be some good coin shows to try to attend? I'm interested mostly in US Coins. My first coin show was the Baltimore Expo this past March. The Winter Expo is Oct 30th - Nov 2nd and might be a good choice.
Better bet would be to find one on a Thursday or Friday and extend your trip to go to the show the next day. I have done that once or twice. Trying to go from training, (and usually they end 4:30 or 5, then rush out there to try to get to a show before 6 would be impossible in most cities. Just take the next day off and extend your ticket to the next day. All you have to pay for is a hotel one night, (and the coins of course).
