Porta Potties on the move.

Went up to Barrie on Sunday, and when we got onto the highway we saw these in front of us:

Managed to get a bit closer, as they were travelling at 120 km, so obviously they were all empty:

Finally caught up with them when they slowed down to turn off the highway:

My dad used to drive a truck delivering brick and stone to building sites, where there is always a porta potty.  Have to say he had some really funny stories about porta potties and building sites.  They were forever being knocked over or backed into!!  The porta potties I see the most of tend to be blue or green so orange was a new one for me.
