Waders and wading boots...now there's a fuzzy ROI. Odds are, no matter how well you treat your waders and boots, you can be pretty sure your grandkids won't fish in them. But you can spend as much for waders and boots as you can for a nice rod and reel. Thing is, waders, like flies, are critical for fishing in most trout rivers (except in the golden summer months when you can wet wade). And wader life depends a lot on luck. Walk into a barbed-wire fence, and you've just flushed away a lot of money. So it's ultimately on you to make your own wader ROI. Still, I've had waders that cost $400 and they started leaking after a month...and I didn't remember any accidents that caused that. You have to think that if you're spending $10 or more for every river day you actually fish in waders, you're getting ripped off. Then again, I've had a pair of Simms G3 Guide waders ($430) that I've fished almost 400 days in...and doing the math, that ends up being an ROI of just over a buck spent for every dry day on the river.
