I did a review on my Source Hydration System. I have only used water in it so far because I did not want to have to deal with the mess that Gatorade and the other energy drinks might make. Here is a good video from Backpacker magazine with some tips on cleaning your drinking system.
On August 11, members of the Canmore Museum and Geoscience Centre will be hiking with the Burgess Shale Foundation to the Trilobite beds near Field, B.C. There are some spots left. There will be 2 groups of 15. Not exactly the way most of us travel but its the only way to get to see this famous bed. Cost is $40/person plus one needs to be a member of the museum (30/year/family). Transportation is not included. I thought I would mention it here. Their URL is www.cmags.org.
