Quiet time in campgrounds is typically 10 pm to 6 am, and in some places like the State Fair Grounds it's 11 pm (because the fair closes at 10 and folks need time to get settled). Heck, the quiet time in most cities is 10 pm to 6 am. I don't see anything written down in Seward's web site about quiet time hours but common courtesy says you don't play guitar and yack around the fire until midnight in the tent camping area, and obviously when other campers have crawled in their tents. Or justify it's okay by pointing out you have camped around more rude people before.
