Hello all, Richmond native here - I'm back from school in SC for a week to spend time with the family. I do most of my fishing on the Mattaponi, but I recently purchased a kick boat for trout/smallmouth/striper fishing in SC. I was thinking about taking that down to Briery Creek for a late afternoon/evening trip for topwaters at sunset type deal. Would this be doable? Also, I have read on the forums that finding the thermocline is crucial (I mean duh it's August), but I dont have a depth finder on the tube. Also, not asking for anyone's honey holes, but where would yall recommend one to put in to best maximize time on the water, especially for topwater action? Thanks in advance.
