Late seeing this post, but wanted to chime in anyway. I love to fish, but it was my older brother that got me started. Now that I'm a dad, I think the best times I've had with my kids is fishing. It's a quiet time, outside enjoying nature with all pressure and stress left far behind. Actually catching the fish is a bonus. The refrigerator at home is covered with pics like yours and it will bring a smile many years later. I don't think your granddaughter will ever forget the time fishing with you. Hopefully she can pass on those times to her kids and grandkids.
Just tickles this old anglers heart a tad.
