I saw someone compare hunting expenses to a round of golf in the forum. As a golfer, this hit me.
If a nice course cost $50 to play, I don't bat an eye, and play as many different courses as I can, when I can. This year alone, I've driven more than 3 hours 1 way just to play golf course on my bucket lists 3 times. The cheapest round cost $175 (the others I'm embarrassed to even say).
Green fees, lost balls, food, gas and vehicle depreciation make this WAY more expensive than my hunting hobby, and this includes annual dog expenses (after the initial investment and training costs).
I'll never balk at the cost of ammo since I sleep in my own bed every night, drive less than 600 miles during an entire hunting season and get to hunt 25+ days a year in my own county.
However, I did draw the line on TSS shells. Not because the $5/shell for a dead bird, but because I miss enough that I'm afraid I'll put too much pressure to "not miss" leading to more misses. (Similar to not playing a brand new ProV into an island green.) Besides, my dog enjoys a good chase on running birds as much as I enjoy watching her!

Another reason I have no problem carrying a 28ga in the field, even in late season, once in a while, just for fun.
