I was told, last summer, that $3 Bridge area has the highest concentration of trout in the whole Madison River. Also, I was told to fish upstream from the bank, or with minimal wading. The fish are right up against the edge (it's 18" deep right off the bank). Look for rocks and seams, use plenty of wight, and don't forget the thing'a'ma'bobbers. Upstream from $3 Bridge is public access on both sides. Downstream is public on the near side (right bank), but private downstream on the far side (left bank).
