Hi guys, my near neighbour is a mad keen fisherman/angler and started the licence process, he almost immediately came up against the need to get a combined hunting and fishing licence, which was explained to him as long and drawn out and expensive.
Had he been able to get a simple fishing licence which may or may not be a simple day fishing, day boat licence he'd have been a happy bunny, day fishing is casual, day and night fishing, serious stuff like he used to do in the UK as in away from home 3/4/5 days at a time as ya'll may appreciate is the proverbially "different kettle of fish", no pun intended.
