Rob chose well to spend his last bachelor days hiking in the mountains. We decided to hike around the Skoki area in Banff National Park.
Aside from the beautiful scenery and tough hiking, the definite highlight was fresh fish every day (caught a few meters from where we camped).
One day we tried to build a raft which failed miserably. Next time, try a lot more rope and less rotten wood.
Pushing over trees to make bridges over rivers is also much more difficult than it sounds. Watch that the bridge doesn't wash down the river during construction.
