I'm not sure if you saw him since he was pretty much working solo and finished after you split but the new guy, Joel, was there whacking for about 3 hours. Joel is the guy who wore the FORC jersey in the Quad City Criterium. If I may be so bold as to suggest a nickname for someone, I'd recommend that Joel by hereby known as "Critter."
In addition to the places you pointed out, I also noticed the Green trail that goes around the Watermelon could use a whacking.
