There is a big rivalry between the 3 best bands in Southeast Texas which are Lumberton, Bridge City, & Little Cypress-Mauriceville. L-Town & LCM has always had a thing between the two groups but that sort of ended when Lumberton moved up to 5A in 2014. That's when Bridge City & LCM started their rivalry and then by 2018 when Lumberton dropped back down to 4A, it escalated from there. You could say that since LCM has not made state since 2018, that the rivalry could be the other two bands, but I'd still throw LCM in there for being consistent and right there behind L-Town & BC. I don't really see this ever changing unless a group moves up/down and doesnt come back to that class for some time.
