Has anyone been to a general admission concert @ Grey Eagle? I've never even been on the property but I'm wondering about the concert experience if it's general admission (no assigned seating). Is this just going to be a sea of people standing & pushing to the front? My issue is that my kid wants to attend the NF concert there (yes it's all ages) but he's only 5' tall. If it's just a large crowd of adults on a flat floor he isn't going to see much of anything so what's the point.
