IIRC building 38 is the long building over off of Weiland Rd. Scroll to the left on the map in the link and down a bit to where 390 and Ridgeway Ave cross. Look up just a bit to the right. it's long and narrow. But never having worked at Kodak Park my building numbering may be off. I forget what number building is at the corner of Lake and Ridge.
The Park has been decimated! Perez certainly has done his handiwork well.
