In the words of Gene Hoffman, our fearless leader, you can never NOT be a be a member of the NRA.
In fact, donating to other organizations before being a member is just plain stupid. Yes they could be more effective per dollar, but they can move mountains. Please think about signing up yourself and everyone you know. I renew my mom, girlfriend, dad and myself every year and try to get the bass pro cards. I also make an additional donation to NRA-ILA and NRA foundation as well.
I urge you to do the same.
