Arrived in Phnom Phen last night after 30 hrs of travel from Medicine Hat.
Lots of scooters, some with 4 people on them, some pulling fifth-wheel type devices as taxis. Most of the 'taxis' though are just plain scooters, ie balance your backpack on there somehow and hang on while the driver weaves through traffic.
No helmets, no protective gear, traffic going every which way, at night half the people are driving without lights.
And I can rent one myself for $5.00/day!
