After my original post here, I had my favorite concert the year after in 2016, where it was that festival I talked about, but they improved it a ton, and it had a crazy lineup for myself. Megadeth, Anthrax, Lamb of God, and Ghost were the main ones I went to see and it was incredible. I stayed for the whole day till the night and ended up leaving at Rob Zombie closing for the night after like a song because honestly I was just worn out. They had a day 2, but I didn't go as there wasn't enough bands that excited me compared to the first, though there would've been a couple I would've enjoyed at the time like Pennywise, Disturbed, and Trivium.
Sadly the people involved killed that festival two years after that because they were greedy money hungry idiots that moved the show to a different city, near Fort Lauderdale, and had problems because of it. The music scene has been dead here since then for the most part which is so frustrating.
