The Cleveland Gladiators, part of the struggling Arena Football League, kick off their season tonight at 7 at the Q. The league has diminished over the last couple of years and only a few teams remain, the Gladiators being one of them. The high-scoring games can be good fun, and the season opener launches with an Outdoor Fan Fest on Gateway Plaza starting at 5 p.m. There will also be a magnetic schedule giveaway, and concession specials include $1 sodas and $2 draft beers.
