Rahway River TU has fly tying nights typically twice a month. We have one tonight. The dates are usually posted here:
http://www.rr-tu.org/ or on Gardenstatetrout.com. It's free and fun...Stop over. I'm sure you'll learn something.
We get everyone from kids to Catskill Fly Tyers Guild members. You should feel comfortable just walking in, but if you don't, send me PM.
