You have been allowed to apply for as many hunts in the category as you wish since 2014, youth hunt were modified in 2017? because people were abusing the system.
Curious, how was the system being abused?
My understanding is that it was being "abused" by people applying for lots of hunts in the youth category because there was no application fee and no hunt fee. So that flooded the system, but the "abuse" was that then those people would not even show up for the hunts and they were ending up with lots of empty slots on hunts that were not being utilized. So the limit was put in place to encourage more responsible application which was believed would help the show up, and therefore, utilization rate of the hunting opportunity. It is my understanding that has worked pretty well, though the no show rate for the youth hunts, presumably because there is no skin in the game due to no fee having to be paid, is still much higher than the adult hunts that have a hunt fee.
