I only got back on the horse a couple of years ago (just flying privately now) and in my "renewal" to get the MECIR it was surprising to see the DGA as a whole separate endorsement with it's own recency... that's what they call progress I guess.
That's because people kept running into the granite!

PS: Interesting, and perhaps a little worrisome, to see people who presumably are doing renewals ever 12 mths or so, who DO NOT know the rules!
