Robby Denning’s book
David longs book
Kurt Darners book
Valeruis Gheist is always pretty good but quite technical
And I’ve heard the book mule deer quest is good but haven’t read it yet.
There is quite a bit of stuff on YouTube. Some good Podcast. Read as much on various mule deer forums. I wouldn’t support kirt darner in anyway or buy his book. The guy is a fraud.
