On July 4, 2010 a delegation of Canadians entered the USA to travel to Cuba as part of the Pastors for Peace Friendshipment. Over the years, hundreds of vehicles and tons of supplies have been shipped to Cuba in an effort to break the blockade, and to raise awareness about the immoral policies in the USA. I have more about the event here [http://olyblog.net/pastors-peace-cuba-caravan-annual-friendshipment-border-crossing-canada].

Here's a bunch of photos from the trip:
