Check out the website to the Ottawa IBM Ring: www.ottawamagic.com
You will find a bunch of great guys that meet there twice a month.
You need to be invited before you can show up. Send an email to the President, or better yet the Treasurer (he is our host).
Our Ring has been called one of the most knowledgeable due to the high calibre of members.
I even drop-in every now and then ;)
