At first glance it looks like a normal construction site. Earthmoving equipment proceeding orderly toward a pesky hill slated for removal, and workers in fluorescent vests waving operators past the caution tape and barriers toward the jobsite. The only incongruity is a bright, lime-green 1959 Euclid TC-12 bulldozer rolling past an orange 1928 Wilford Model B shovel.
And for every familiar CAT logo there is a Bucyrus Erie or a Cletrac, with the odd Oliver thrown in the mix. In fact, this one hill has at least two-dozen machines working on it at once, with a growing ring of spectators held in rapt attention.
