I wonder what a decibel meter would read, would Gampel or Hartford be louder?
Irrespective of the capacity difference, domes are generally louder. Anecdotally, the noise never caused me a headache in Hartford, but I'll never forget the one I had in Gampel when Izzo and Cleaves came to Storrs.
For me and others East of the River, it's six of one, 1/2 dozen of the other. Both venues are about 20/25 minutes away. There are more options for parking, refreshment, and traffic in Hartford, but the atmosphere was/is typically better in Storrs. Also the sightlines in Gampel are far superior from anywhere in the stands. I took my son to the Marquette game on Tuesday, but for what I paid and how far we were (S202, RS), I would have rather watched from home.
I can get on board with games in Hartford during break only, but that is only 4 home games. They are going to have throw Hartford a few more marque matchups. Preferably on the weekends.
