Reenactning
3Beavers,
here in B.C. as far as the 19th century goes there is a group in the Lower mainland that does the Royal Engineers from 1858 till 1863. They do a very good job and are into doing a lot of research on their gear. In Victoria a late furtrade group is in the very early stages of being formed.
In Alberta I did the Riel Rebellion and there are various military reenactment groups.
As for other eras there is a very good 14th century medieval English group in Victoria. There is a good Roman group in Calgary.
Joe N,
you were at Slavkov for the 2005 anniversary? I wish I had the free time and the money at the time. I'm actually from old Czechoslovakia and have been hearing good things about the groups that attend Slavkov.
