so my route was cut last spring and part of it was made into an aux route. it is only just over a 2hr a day route. is there a minimum number of hours an aux route can be and what happens if it goes below that? would that be absorbed back to my route or would i have to give up more to keep it above the minimum hours? just trying to be prepared. my route and the aux are rmpo so i don't think any other zip would be involved as it would make a 2 zip route
