COF . . . COF . . . COF . . . well, COF . . . COF . . . since you ask, that would be a yes and a no.
That's a "no" because AARP's politics are, well, let's say, not our style.
That's a "yes" because of the remote chance that AARP might, just might, offer a benefit sometime that makes the dues worth it.
Hasn't happened yet, so might be a double "no" one of these days.
If you would like a recommendation for a good way to "invest" in joining something, and get a "for sure benefit" in those Golden Years, check out a life membership with Trout Unlimited.
You get a nice Winston rod and Waterworks-Lamson reel with that membership:
Together, the rod and reel are worth a big chunk of the life fee.
Plus, you know the rest of the fee goes to a good purpose. Or, you could waive the rod & reel so all of the fee benefits fisheries, and get full tax deduction.
Don't believe AARP will ever give out a deal like that.
