The number of active hunters is decreasing.
Main reason (IMO), we're not recruiting the kids into the sport. Several reasons for this; lack of interest on the part of todays youth, too many single parent households, indoctrination by the media and public schools among others. The good news is we can reverse this trend, the bad news (to some) is that we are going to have to work at it and spend some time.
We need to get the kids interested in the outdoors at a young age. Turn the T.V., computer, Ipod, whatever off and get them outside. Not on the diamond or court or soccer field, out in the woods. Show them the animals and how they interact. Explain stuff to them and then show it. Don't just limit this to your kids, take relatives or neighbors' kids (with permission of course).
Best thing for kids (when they are mature enough) is a squirrel hunt. Lots of opportunities for a shot and not as tough a hunt as deer or other big game. Keep it fun and interesting.
If you know of a single parent household ( and in this day who doesn't) ask if you can introduce the kids to the sport. Lots of children may be interested but the parent lacks the time or interest to take them.
Spend some time watching what your kids are watching on T.V. Most programing aimed at children (or adults for that matter) portray hunting and hunters in a very negative light. Public schools tend to do the same and are very anti-gun. You need to be sure that your kids are learning your values.
People want to complain that hunting has gotten too expensive or that there's no land available. In case you haven't noticed, everything has gotten more expensive.
I'd be willing to bet that every state in the Union has some type of public land open for hunting. Visit it through the week or spend a little boot leather getting back from the crowds. Look for alternates to the hard hunted zone. Most hunters rarely get too far from a road or other access area. Hike in a half a mile or so and you probably won't see another person.
It is possible to take a very nice animal on public land, it happens every year. It takes some hard work and dedication.
