I happened to be on the Hackensack River Walkway on April 17 and saw canoes in the water. They appeared to launch from the Teaneck side of FDU (first picture).
A little further downriver, I saw that they were Hackensack Riverkeeper canoes and that the students were picking garbage from the water (second picture). Note that while one picks something out of the water, the other isn't holding an oar - it's a net.
I checked online and found out that this was FDU's 5th annual Earth Day river cleanup.
The other pictures are some of what else I shot on the Walkway that day. The last two pictures show that some angles are better than others. And if you look closely at the next-to-last one, you can see part of the new building at 29 Linden - something I didn't think was visible from the Walkway.
