I don't live in the US but has been an AMA member since the 70's.
AMA did a great job for the hobby in the last 60-plus years and continue to do so, IMHO.
I was Vice President of ABA, the Brazilian equivalent to the AMA, and got a lot of help from the guys at AMA, still in Reston, VA. We were in the process to get frequencies protected for our hobby and what AMA did in the US helped us a great deal. R/C flyiers in Brazil have the same frequencies you have in the US and AMA was very important to achieve this. You should be proud of you national organization.

I have a vacation home in North Central Florida for a number of years and belong to two local R/C clubs, there.
I vote in every election and did it again this year, when we put a good person on the EC.
I believe in participation. I do care. I vote.
