You can discover your pond on foot or afloat. Either way, you want to circumnavigate its shoreline. Get a pocket notebook and then roughly sketch the outline of the pond on three or four pages. Then head for the pond. If you are afoot, go prepared to wade.
Some land owners take umbrage at having fishers in their backyards.
As if we might damage their sand with our footprints or ask to use their bathroom. No problem, just step into six inches of water and continue on your way. Smiling shyly and saying good morning helps. Chest waders are best because shorelines have a way of dropping off or becoming, let us say, soft. Chest waders will keep you dry but wearing an old pair of jeans and tennis shoes will do when the water warms up a bit.
