Over Memorial Day weekend, Boo and I walked around Inwood Hill Park (pictured above) and with its steep trails, it is definitely not a "walk in the park" (wah wah). Then the next day we took the train up the Hudson and hiked 4.8 miles in Cold Spring. Talk about steep! At one point I felt like I was just scaling rock. I later found out that the Cold Spring hike was classified as "strenuous". Good thing I didn't know this prior to the hike because I would've bounced to the ounce.
Sometimes to get to the top, you just gotta be confident that you'll make it there and not worry about how hard it is.
However, I should add that even though I did not know the hike was "strenuous" I could still tell it was very, very strenuous and I had no qualms telling boo that I felt this way the entire hike :)
