I have, honestly, only been fishing twice. Both were on one of our pre-children cross country trips; once in Yellowstone and once in Oregon. I got the hang of casting but it was Andy that, on the second outing, caught a rainbow trout, cleaned it and cooked it (barely, yum) on the camp stove. That was the freshest fish I have had, clearly, at about 20 minutes post-catch.
Miryam showed some interest in fishing so on a trip back from Maryland Andy brought her a rod and small tackle box that all fits in a carrying bag for her back. She was very proud and very excited to give it a go.
She picked up casting surprisingly quickly and caught a sunfish on her first trip out with papa, but so far nothing for the frying pan. We found a company that sells biodegradable fishing line and other earth-conscious tackle so we can impact the rivers as little as possible while we try to catch our dinner. We've been reading over the Fish section in the River Cottage cookbook and dreaming of meals to come.
