I know it looks like that but have been watching them for a couple of weeks now. They really do work hard. It's a large plot of land (for NYC), plus the high temperature and humidity does not help.
This lens just amazes me as I am shooting from my 5th floor window. Hardly did any processing on this one.
Thanks, Mike!
Take care, Lilia

...the men appear to have trained their shovels to do the work for them,
great shot Lilia !
