At each of the following stops there is a dedicated vendor that will give you a stamp on the paper that was sent to you when you signed up for the en-route poker run. When you get to Whitehorse and check in at the Rally Venue you will pull cards to try to make the winning poker hand!
The enroute stops coincide with only some of the recommended gas stops. Be sure to check the mileage charts as it may be necessary for you to make stops in addition to these. Personal experience on running out of gas on the Alaska Highway confirms mosquitoes have their own early warning system and will be waiting for you in droves!
The Northern enroute poker run from Alaska has been cancelled due to lack of participation.
