There was a Dryland Challenge sled dog race near me over the weekend, so I went to it, and so did PT member *sled_dog*(both days .) It was a blast, there was canicross, bikejoring, and cart races. They had teams(for cart races) of 4, 6, and 8, and bikejoring teams of 2. When the dogs got hooked up, they went crazy!!!! It was a great thing to go to!!
Here's pics and a video link.






Ouch, this person got dragged as the team took off!!

Here's a movie of them being hooked up, make sure to turn your sound up, but not too loud!!
