What do these mean?

[skymama 35]

When a skydiving friend signed off on a note to me, besides writing his license #, he wrote these things:
MB 2603
HF 16
CSA 466
Being the big tease that he is, he won't tell me what they mean now and it's driving me crazy trying to figure it out. Can anyone tell me what they mean? I'm sure it's something that should be quite obvious, and I'll think, DUH!, but I can't get it.

Skymama, was this an instructor writing comments in your book?

no, he's not an instructor. He's just a friend who wrote an e-mail to me. They were listed under his name. He swears they pertain to skydivng, and that they are real things. Other than that, he won't give me anymore clues. He enjoys aggrivating me!

Oh, some help you are! Don't you tease me too. Take pity on me, I'm home sick today and am coughing my brains out.

MB is probably the Muff Brothers' club. I am not really familiar with it so someone else will have to fill you in. It is a fraternity of sorts though, from what I understand. The other two I don't know. Could CSA be something Canadian?

Ok, now I'm really intrigued. Whatever kind of club the boys have, we want one too! Right, girls?!
That's a good angle you're looking at there Sis, but he's not Canadian.

Is he a Christian? CSA could be Christian Skydivers Association.
MB is probably muff bros. http://www.muffbros.com/

Skymama,
You don’t have to be a guy to get a Muff Brother or a Freak Brother license number, all you have to do is pass the initiation.

I have never heard or seen any of those before. He could just be screwing with you, but its very possible that CSA is the Canadian Skydivers Association, if there is such a thing. He got me too.

Like others have said MB I'm sure is Muff Brother. HF could be "Hell Fish", not sure what this is all about but have heard skydiving references to it. Not sure about CSA though?

There's not... we are members of the CSPA, Canadian Sport Parachute Association. But CSA is the Canadian Safety Association!

I was close!! Shows how much I know about Canada. I went there once. Thats about it. Skiing in Whistler! It was the best ever. I change the subject too much don't I? Sorry. Carry on.

hi all-
just heard from my friend. You were right about the MB and HF. Beer to all of you who clued me in. Now, what about the last one-CSA?

The CSA is the Christian Skydivers Association. Its an actual organization, still fairly new though.
