Join the Garand Collectors Association: http://www.thegca.org/ It is $25 per year, and you get a quarterly journal with TONS of Garand info and pictures. Plus it satisfies the CMP club requirement. If you make a trip to the North or South store you can join the GCA at the store and if will satisfy the club requirement. There are 2 other main requirements: Be a US Citizen (I proved this with a copy of my birth certificate) and have proof of a "shooting activity" (CCW license, hunting license that required a shooting certification, C&R license, ect).
If anyone is pondering making a trip to Anniston DO IT!!!!!!!!!!!! It is great. I was there 3 weekends ago and they had alot of decent field grade garands (good shooters) and lots of rack grade (ok quality) and service grade (good shooters) M1 carbines (Inland and Underwood manufacture). Jan 7 they will start selling Winchester, Quality Hardware, Rockola carbines in the 2 grades. There will be a small quantity of each available in the stores when they go on sale.
Next Saturday (Dec 15th) is the last Saturday the CMP stores will be open. They are closing for Christmas and will reopen in Jan Wednesday-Friday only. I asked why and Mr. Orest Michaels the director of the CMP told me it is because the CMP was chartered mainly to promote shooting activities and provide rifles through the mail. The stores being open to the public is just an added bonus I guess.
Here is a link to the "South Store" forum on the CMP website: http://www.odcmp.org/new_forum/forum.asp?FORUM_ID=31 Folks often post info on the inventory at the store.
