We went hiking at Chittenango State Park in NY today to test out the back pack we got for our Pyrs. Tache has fell in love with it the moment we put it on him for the first time; he got giddy like a puppy. We had him carry 4 bottled drinks; a tea for myself two propels for my gf and a bottled water for him. He also carried his own water dish, our camera, and cell phone. The falls were gorgeous!!! We hiked for about 30-45minutes before we decided to head home (It was 14'F).
