I've only really fly fished out west for trout, but my favorite is chasing brown trout in the fall with streamers. In late June I will be going after bass and pike in the BWCA for the first time! Bucket list is going down in the Caribbean and fishing for tarpon and bonefish.
I've caught a crappie on a black wooly bugger down here in Wisconsin that put a surprising fight for a 5 wt. It's been the most memorable fish as well since I was fishing for sunfish and bluegills and did not expect to get a crappie.
