Here is the subject from a Gun Club Newsletter recently:
Frozen Chosin Match--February 18th, 2006
Once again it is time for all gas gun shooters, new members, old members, and guests to join again for the third annual winter match in honor and memory of the Marines ordeal in the frozen mountains of North Korea, December 1950. Remember, this is our time to play dress-up, so go find all that moth-eaten gear that is appropriate to that time period, and show up at Noon on the 18th for another great time. It will make you appreciate our summer matches even more. New members are encouraged to participate so grab 50 rounds plus any practice ammo that you need and show up at the 100 yard range ready for a little challenge if the weather is a factor.
From what I could tell from the photos from last year's match, it looked like kind of even between the Garands and ar15's. Looks like around 21-22 shooters showed up last year also... I will check with the match director and find out if the gate will be open or will you have to be with a member as a guest if you are not a member of the gun club.
edited to add that the gate will be open and you do not have to be with a member to shoot...
