Old Bay Seasoning
Can I find any in town, or would I need to travel south of the Mason-Dixon line to get any?
Don't know offhand and the McCormick product store locator only works for the US, but you could try contacting them directly to ask:
1-800-632-5847, Monday - Friday, 9:30 a.m. - 5:00 p.m. EST
contact form: http://www.mccormick.com/content.cfm?...
You can also buy Old Bay in their online store in several incarnations: http://shop.mccormick.com
My IGA carries it- so maybe you want to call the one in your neighbourhood and ask (mine is the one in the Cote st. Luc Shopping Center).
Many fishmongers sell it, so check nearest you. I know that Nouveau Falero on Parc at Bernard sells it.
