Chinatown and Gold Coast

I wound up in Chinatown one afternoon. Something was calling me there and I wanted to browse a bit. I went to the shop I had in mind and was poking around here and there, trying to find what I had in mind. As my eyes adjusted to the dimness, I saw the owner hunched over the counter, counting inventory and someone browsing in the back of the store. I headed first for the giant Buddha statue then to the beads, making my way towards the back. I adjusted my bag so I wouldn't knock anything over and saw some figurines that caught my eye. As I perused them, I started looking down the aisle at the other items. I realized that there was no one else in the shop besides me and the owner. I glanced from side to side and there was simply no one. I can't describe the person very well but I would challenge anyone to describe someone they saw turn the aisle in the grocery store. It was like that. I picked up the figurine that caught my eye and left.
I later wandered around the Gold Coast and stumbled upon a slough off of Lake Michigan where the city just melted away. It was an oasis of tranquility amid the hectic hubbub. I spent a few minutes (or longer?) there and soaked up some awesomeness. When I got up to leave I noticed a very large black shape like a cloak or skate leap from a nearby building and disappear behind another building. I kept my eyes open but never saw it again.
