Since 2002 (after 9-11-2001) they put up a fence and have done bag searches and have claimed to prohibit weapons.
I lived in Vancouver during this time and as a kid and had always gone to the for or nearby.
When they put up the fence I announced to the family that we would no longer be waching at the Fort.
I refused to be inside a fence if there was a terrorist or other problem. I did not want to feel caged in!
There are many places that are free, and outside of the Fort that the fireworks can be viewed. Many times we went to Clark College and found a place on the grass to watch.
