i know exactly how you feel. i absolutely hated many aspects of drum corps when i marched. it was probably the worst thing i ever did. yet, the only reason i didn't march this past summer was due to financial reasons. in the end, you find that its addicting and worth it and no matter how many reasons you come up with not to march, the rewards of marching are always worth it.
then again, its something you have to experience, not told....so yea, march.
