This was the first time hiking Mt. Si for my husband and I. My brother was our tour guide. My brother warned us saying, ""It's ass-kickin',"" and he was right. At first, we were laughing and joking around, greeting everyone with an enthusiastic ""Hello!"" However, by the time we were on our last 1/2 mile we could barely work up a smile. When we reached the top we rewarded ourselves with energy bars and plenty of H2O. We then quickly jumped to our feet, and ran part way down the mountain, twisting a few ankles here and there. When it was all said and done, we felt sore, but satisfied. Tough mountain/Fun hike
