It's getting a little late to be flying, and a round trip from Vancouver to Edmonton and back again would run you about $500.00 at least.
However! The lovely Greyhound can get you there and back for the low
low LOW price of $321.00, tax included!
The bus trip is a thrilling 15-17 hour ride in their luxurious stage coach, likely to be driven by a lonely old man and guaranteed to have at least one pack of skiing enthusiasts on board.
Or, on foot, you can run across the Rockie Mountains in just under 60 days--50 if you really push yourself!
