On Saturday, I was in Edmonton, visiting friends, and we decided to go to Pembina River Tubing. Great idea!
My advice:

• Bring Beth along. Her willingness is optional, but you must bring her. She has river rafts that are much nicer than the ones rented by the company. And apparently, they cost as much to buy as it was to rent the small tubes that you would normally ride around in.
• Bring two cars. The bus that the company uses to ferry people is often crowded with lines, and you have to sign a waiver to use it. Which means you have to wait in line with all the other plebs. It is better to leave a car waiting for you at the end to ferry you and your friends back to the start.
• Bring food. It is great to just float on the river, munching away.

Looking at this advice, it seems designed to prevent giving the company any money.
In any case, it was one of the hottest days of the year. If I had gone with the original plan, I would have been running the Sinister 7 instead. That plan was abandoned months ago when I just wasn’t training enough. It seems to have worked out for me.
I wish I could have taken pictures, but it was on the water. I wouldn’t have trusted a camera to survive.
