I want to say welcome to the forum because your other posts have escaped my eye. It is always a pleasure to get positive feedback like what you have written here
I wrote the short story of what inspired me and how I began fishing on the profile page here. Rather than copy it to here I would invite you to put your cursor on my screen name and tap, choose public profile and the tale is told. Your approach will get you into fly fishing, reading and then taking what you learn in theory to the river or creek and turning it into practice is a time proven means for people to learn about fly fishing.
I hope you will continue reading here and post often. Questions are the life blood of a forum such as this and there are many experienced folks here who will lend you a hand with anything you come up with.
