Many, many smile-y other walkers, joggers, and cyclists.

Squirrels either playing a game called "how many leaves can I fit into my mouth at one time" or building their nests for winter.  I prefer to think it's the former, and I'm positive I saw the world champion squirrel.  (I was sorry I didn't have a camera.  It was laugh out loud funny.)

A dogwalker with 9 dogs, ranging in size from spaniel to great dane.  Only two of them had leashes on.  

 A puppy who was very, very happy to see me.   I don't think it was anything personal.  This puppy was obviously just very happy to see everything, and a funny contrast to the orderly dogwalker dogs.

Someone's lost keys, carefully suspended from a tree branch at eye level.  (again, I wish I had my camera for this.)

Leaves swirling around through the sunlight.

Now, I say all these things because I nearly stayed home.  My legs are sore from a weights workout on Tuesday, and I was sitting at my desk trying to rationalize another day off from exercise when the sun came out (it's been cloudy all day).  I took this as a sign from heaven that I needed to go for a walk rather than go to the gym and use the elliptical.  Halfway through my walk, I realized I hadn't exercised outside on this trail a block from my apartment for the entire summer.  I think the last time I used it was last September.  Wow.  I realized this because I felt incredibly blissed-out by the experience of walking outside among the birds and the squirrels and the dogs and the other people, and yet I had deprived myself of it for the entire spring/summer.

And, my legs are a lot less sore now.

When in doubt, workout.  Always, always, always.
