As you'd expect from a wanderer, his photos hail from all over the city. But I have a particular fondness for his local shots, such as these three taken right here in Riverside Park. You may recognize the site as the traveling rings playground which is down at the river sandwiched between soccer fields at the level of W. 105th Street. The rings have a wonderfully community-minded history, thanks to Dorlene Kaplan and her husband, and the Riverside Park Fund. It bears retelling that back in 2002 this section of the park almost became an "adventure" concession called "Adrenaline Heights."
If you've never been down there, stop by and take a look at the paragons of upper body strength swinging freely from ring to ring. The folks who make the traveling rings look easy are poetry in motion. I've never seen a hula hooper down there, but after coming upon Bob's shots, I am going to keep my eye out for one, as well as for unicyclists, stilt and tightrope walkers and jugglers...all denizens of this little hidden nook of Riverside Park.
