Usually we would come in through Beiserker, to the 2, then exit off the 2 through Airdrie to Cochrane then down to the Trans Canada. Avoids a lot of high way and Calgary traffic.
Here is the usual route give or take
There is a strip between Kindersely and Hannah where you wonder if life is worth living anymore, but after that things pick up.
I haven't tried taking Stoney since it was completed though and have heard from others it is a lot faster and not bad for traffic. The only people who come in on the Trans Can belong to this hole in the ground called Regina. Also I avoid Drumheller at all costs.. I had a bathroom 'incident' there a while ago involving a nasty heroine beer induced poop where I may have scarred a little boy for life.
