It should already be there, I visited in January.
I could have sworn I uploaded those photos on here, but apparently not! Jobalba, the address for Johnson Park is 1030 River Rd, Piscataway, NJ. Might as well add Thompson Park as well then, too, and I'll post photos for both. It's in Monroe Township, I can't find an address but the coordinates are N 40° 20' 36.135", W 74° 26' 10.4454" (Directions to Thompson Park)
