July. Last year was my first year and I really had a great time. The best part was the tent sale. Just don't get there for 9 am. I did that with my cousin and her husband. My cousin was a pain. The only reason why she went was because she wanted to go to the Cracker Barrel (IDK if there are any in CAN, but they have good coffee and is one of the "country/rural" style places). It would have been better to go there for Daneyko and the grab bag (I think was noon-1:30), then lunch (Cracker Barrel, ~20 minutes away), go to the Expo for two hours, then to Meigray Facility.
Also, save up some money for the tent sale!!! I left with 3 jerseys from the tent sale ($75) + grab bag ($51) + entry jersey ($25). I wish I could have bought more, but I bought my white Isles EDGE 2.0 draft jersey the week before (which was a steal)
