Another "situation" that needs work, judging from the success level I have
and see around me

Come up to the Firehole in late June and late in the day. Fish the area
downstream from the Firehole picnic area about 1/4 mile and on down a good
ways.

There is some activity that looks like fish on caddis that drives me nuts
.... patterns that work on the Firehole, late in the day, late in June, when
it looks like the fish are taking caddis, don't work. These are really
pretty small fish, but the problem is still intriguing
