Trout Bum, and most of Gierach's books are some of the most subversive things you're going to read. After finishing one of his books, I have serious thoughts about quitting my job, loading my stuff in the back of an old pickup truck and heading out to fish (forever) leaving my job and desk just a distant and very bad memory. The other side of the coin is I have a 13 year old son that will have college expenses and a wife that I'm rather fond of. I believe if I chucked my job and went fishing my loving wife would, rightly so, have a few less than positive things to say about the situation.
However, John's books are very good. I'm about 75 pages into "A good life wasted" right now. It is entertaining so far with a pretty eclectic cast of charactors. I don't think it's as well written as the Gierach books but it is entertaining and a fast read.
