2019 Card Shows worth traveling to for graded vintage?

[1954 topps]

Hi All,

Seeing a card in person before purchasing is an awesome experience you just don't get through winning an auction online. I'd like to get fellow collectors thoughts on large card shows worth traveling to for high grade vintage. 50's in 8's or higher and E sets in 5 or higher are my interests. I'm often disappointed after traveling a good distance to a show to find almost exclusively raw cards or low to mid graded inventory. Looking to plan ahead and select 2-3 card shows to travel to in the coming year. I'm not afraid of long drives or possible plane ride to get there as long as the inventory is worth the trip!

I'm in Massachusetts so east coast to mid-west are my typical targets.
I've been to the following: Wilmington MA, White Plains NY, King of Prussia PA, Strongsville OH, smaller New Jersey shows, Cincinnati OH, Glen Burnie MD and the typical National sites of Rosemont, Cleveland, and Atlantic City.

On my radar for somewhere new in 2019 is Chantilly VA, Columbus OH and possibly even Shakopee MN. For those that have visited these larger ~300 table shows, can you provide any feedback?

Perhaps there are some great smaller shows that have a large graded vintage/prewar presence that aren't on my radar that I should consider?

Appreciate your feedback and happy hunting!
