Here we are setting the first face - actually the rear billboard face - and preparing to plumb and fill the post holes. The holes have been cut and bored for the second face, but not in the proposed location.
The evening of the first dig, the first five post holes were dug fairly quickly; on the second set, however, we quickly ran into a number of large concrete obstacles - leftover sections of the Park East Freeway.
Rather than fighting the concrete and rebar that appeared early and often (and existed to unknown depths), a decision was made to reconfigure the piece, forcing a lot of quick redrawing and planning. Fortunately, the second set of holes were relatively easy to dig, allowing the second design to take shape.
