A year ago, I posted on the best resource on the web for collecting OA Memorabilia issued by the Northeast Region.
Dave Scocca who is a regular commenter to this blog and on Patch-L has a web page which may be of interest to NY and other Region 1 and Region 2 collectors.
For those who collect issues outside of there own lodge or lodge issued memorabilia, the next step up is typically Area and Section Issues. Dave has gone one step past that with a compilation of Order of the Arrow Issues from the Northeast Region. His checklist can be found on his Northeast Region OA Patches.
