Never heard of 100 yotes in pa... but, If somone had the time and ambition (laid off, retired, professional), and put the miles on from day one, I don't see it being some impossible feat.
In the one animalistics vid, I think he states that he catches upwards of 70 while working full time; but he also said he has sets out from the first day to the last. I spoke with a guy from Mckean county a couple years ago about numbers. He told me that he'll catch anywhere from 13 to 70 yotes a year, depending on weather and that years population. (and he's not a full timer, trapping every day)
I'm pretty sure mark zagger (southern new york) catches over a 100 trapping full time for two weeks.
So, if you had: the time, hardware, experience/knowledge, animals, land, and weather I think you could do it. Just my opinion.
