I am pretty sure there has never been a MOC rally in Canada nor have we ever seen a Montana rally. At this point I am not sure of the number of Canadians that frequent this site in particular but it would appear to be a fairly low number.
One day we would like to attend this type of thing but the one in Goshen to us is too far out of the way for us at this point but perhaps if there was a more central rally in Canada, the Dakotas or Montana one might be surprised by the numbers.
Alberta would be a fine place to hold a rally say in late April or early May as we could get a jump on the season with your better weather that early in the season. We love Lethbridge!!!
