Last night a friend of mine was heading into the fraser valley. When he got near chilliwack there was a bike that passed him 2up on the shoulder of the fast lane. The shouler was about to be paved, and therefore was grinded. As the bike passed him, the chick on the back tossed a litre bottle of oil up and onto his window. My friend found out that the bike was stolen, and that there are 3 riders doing this. When the cops pull them over, the bikes stop. As soon as the police officer gets out of the cruiser, the bike takes off.
This is happening between the Port Mann and Young road in Chilliwack.
These bikes appear to be targeting Tractor/trailer units.
If you see this happening, ... feel free to intervene with whatever your imagination can come up with.
