Dont go on saturday, its a fuckin madhouse.
Go Friday stay all day and have a great time.
But on saturday its fuckin crazy, something like 250,000 people walk in and out of the expo that day, its like the whole town of columbus goes there and walks around, its hot, tons of people are farting out those cheap proteins and everyone has extreme ILS, so its hard to move around in there.
I hear sunday isnt bad either, but i didnt go on sunday because i had to catch my plane.
have fun
