Ahhhh, The Journey begins!!! Catfish edge is a good place to start. TFF also has all the info you could ever need on cats (just gotta be able to differentiate from the BullSitters and the guys that are actually out there consistently putting fish in the boat) ...read guys trip reports and most will give you the general info like depth, bait , and type of structure without actually giving you their pins. Find the guys on your lake that chase cats weekly and start building bridges. Having guys to bounce ideas of every week will up your game about as fast as anything. Lastly and most important of all, get out there and chase them every week cause consistent time on water trumps all.
There is a fine line between fishing and floating around like an idiot!!
