Shelters in the South are very full of rodents, always lots of mice, woods rats, and or worse................and way too many people trying to share them.
In the North, it is the same problem ongoing, it's just that Hauntivirus has actually been found here a few years ago, a thru-hiker almost died here on this section of PA years ago.
All AT Hiking clubs should have learned by now, how to set rodent bait stations at every shelter on the AT, or be required by law, to pay expert exterminators to do weekly visits to all shelters, to rebait traps and refill all bait stations, or else just shut them all down due to the unsanitary conditions.
Just like any Best Western, Mcdonalds, or Super 8 Motel,..........Long distance hiking, and The AT, is a huge business, and we all deserve the protection.
End Of Problem
