I was where you were in 2014.
Since early 2014,I have fished the LR about 30-40 times.I have taken six 3 day trips ,so I could spend more time exploring than traveling back and forth from West Chester,PA.
Here's my brief recommendation(all of which I've done)
!) help stock the LR.(through the LRSA)Takes 2 Saturdays in the Spring.You learn all the stocking points ,but most importantly you get a broad overview of the river,access points,parking areas.
2)Learn the safe water levels to wade and start exploring(hopefully with another angler for safety purposes).I have waded some pretty hairy water over the years,but the LR is up there in terms of difficulty.The LRCWA has a good wading guide,AND,a great website for locating access points
3)Wherever you fish,take the time to greet and talk to other anglers.Mention that you are new to the river.You will be pleasantly surprised at how much intel you can get this way.I even met one ff who invited me to join him and he pointed out "good" spots to me.We hit it off and I have fished 4 times with him this year..all at different spots, that I never would have found on my own
4)It is a very big river,so take your time,and be persistent.As Shane Becker says above,he is still learning the river after 15 years fishing it.Be flexible in your tactics.e.g.I haven't fished wets/soft hackles in 40 years.I saw a ff above me hammering them,while I was having marginal success with nymphs.so I decided to relearn wet fly techniques and it has paid off on the LR(and else where).Be prepared to eat some humble pie,as you learn the river
5)Invest in a few float trips.I only did one in 2014,because I couldn't find any one to share a trip.I intend to do at least 2 this year.I'm sure if you post up on this forum(which I did not do),you will find someone to jump in with you
Good luck and TL
