My Dad. He taught me all the basics. Gun safety, ethics, conservation, how to blow a duck call, shooting, etc. I was shooting a pellet gun and age 6, a .22 at 7, shooting the a shotgun at targets at age 8 and at age 9 I was shooting ducks with a .410 in the boat with him. Going along on deer hunts at age 10, hunting deer at age 12 (state law-you had to have passed the hunter safety and had to be age 12), hunting NoDak at age 14.
But I learned much of my current knowledge by actually just hunting. When to or not to call and which call to use, where to set up, how to set up, etc. Much of the modern things just were not around when I started. It was a big deal to even have an OB motor back then, now they have 50hp OBs and 35 Hypers/Muds. Acrylic calls, layout blinds, GPSs, ATVs, Full Body decoys, fairly accurate weather forecasts, and of course the internet/computers and now spinners are all recent events in waterfowling. Heck I taught him a trick or 2 before he died almost 10 years ago. He sure did like the gortex outwear for keeping him dry.
Sometimes I wonder if the "simpler" ways of yesteryear are better... a gunny sack of hand carved wood decoys, an old double pointed plywood hand made boat with a push pole, and a Herters wood duck call with a Winchester sweet 16 model 12 and clouds of ducks to hunt. VS all the fast paced stuff and "plastic" gear currently... and the lack of huntable ducks.
Hmmmmmm..... Newer is not always "better".... I think you guys that are middle aged or older will be able to relate.
One thing that has not changed is the pricks who call themselves "hunters". Had bad apples back then, and they are still around unfortunately.
