You can't fish "all" the time while you're at Newlands [well, unless you're Mike Fink (sixth picture down) with American Airlines from Springfield MO] and there are other things to do here; we have listed some below: 

You can play a game of horse-shoes, or a set of tennis.  Maybe take a canoe out.  Or call in someone to give you a massage

You can go sightseeing, play some golf, or hike one of several trails.  Maybe visit some antique shops.  Or attend church services
