DCA is a good scene for a lot of junior-age guys, too. If you want to drum competitively but have other commitments, can't make the commute to a junior corps, or don't want to spend a few grand, there's no better option. There are also the guys who learn the ropes with an all-age corps before doing the all-day-all-summer
DCI thing (and sometimes returning to DCA).
No matter your age, the DCA scene is a blast. Lots of good guys from all over the country, from different eras and backgrounds, getting together to drum and hang out. What's not to like?
Like
DCI, there's a huge range when it comes to corps' competitive quality. There are the smaller or upstart groups who could be DCA's equivalent to
DCI's former Division III, like the Lakeshoremen. But there are also groups like the Reading Buccaneers who wouldn't look out of place among
DCI World Class corps.
