Tom has written an excellent article about Stealth.
I will visit a river Karvionkoski this weekend. Wading part of Toms article gives great advice for this river. It is a short stretch, about 200 yards or so. One bank is deep, virtually unwadeable, plenty of good rainbows and smaller browns. Its all about taking cover and keeping low profile if there is no cover. Moving slow. I visited this river twice this summer and in both visits one trout darted off from my boots. Embarrassing moments - yet it happens.
