Thanks for the tips so far!
I will definitely be heading to Ommegang, will try see a game downtown and will check out Main Street.
We already have accommodations, but I will check out
https://doubledaycafe.com for food.
The lake sounds fun and the
Farmer's Museum and
Fenimore Art Museum sound interesting.
Unfortunately, I won't be able to hit up the card show in July/August as I will only be there during the last few days in June.
