I'll open myself to embarrassment by guessing at a few:
1) Perhaps it should be バトンルージ市?
2) アメリカの南にあります sounds like "to the south of America". Try アメリカの南部にあります instead
3) Same as #1?
4) Maybe a wa/ga mistake?
5)夏の時 is redundant, sort of like saying "my female aunt".
6) まつりがたくさんある
7) Another redundancy problem, I think.
