If you are fighting a fish and he gets tangled in underwater sticks/roots, just give him some slack and wait a while. I've fought 2 nice trout on light tippet and this tip hasn't failed me yet! For you desert wanders, watch out for rattlers down by the water and also up in the bushes! Thats where they cool themselves. For you steelheaders, check your hook and leader after every snag on the bottom, even if it comes off easily. Sharpen your hook and replace your leader with a passion! You won't regret it. And don't leave a run unless you feel you've covered it well.
