I was a member of the NWTF for years because I was going to their local banquets and the price to get in included your yearly membership dues. I coached our county SCTP program in skeet and sporting clays and we had to have a 503C (I think that is what it was called) and the local NWTF chapter was our sponsor. I felt like I needed to support them as they were supporting us. That said, I quit coaching 2 years ago and have not been a NWTF in the last 2 years either.
I am a life member of the NRA, changed my membership to a life membership back during the Clinton time frame.
