Allen has good points may I also add time to go hunting, fewer people have the time to go hunting, we are not all farmers. Another is cost. A friend pointed out is is far less costly to buy food than to go out and kill and process it. Calculate the per pound cost of your fish and see whether it is cheaper to buy. Don't forget to include the cost of that sparkly boat.
Hah, walleye is now more expensive than prime rib! A couple weeks ago I went to New Town to take my 84 yr old stepfather out fishing. $250 in diesel, $100 in gas for the Toon, another $100 in fishing tackle, ice and other supplies (seriously, $4 a spinner at the New Town Marina = ouch), all to catch 25 walleyes. They were pretty nice fish, but still. I didn't weigh the filets, but let's say we got 12.5 lbs of edible walleye that makes the value of the weekend's catch roughly $450/12.5 or $36 a pound.
As far as time, it sure seems that even the kids nowadays have something going on. My 16 yr old son has "Captain's Practice" three times a week this summer for Cross Country, Sanford Power (athletic training) four days a week, Krav Maga another two days a week, and he shoots Sporting Clays with me in a league one evening a week.
The 14 yr old daughter has the same Sanford Power and Krav Maga but instead of Cross Country she has open gym for Volleyball four days a week. At somewhat seemingly random times.
Yep, there's no real break in school or life's activities during the summer around here.
