The most time-consuming part of updating pages, it seems, is re-counting the order for the photo dates at the bottom of each page. That said, these were from pictures taken in mid-2011.
Pages updated: 62, 111, 113, 142, 202, 221, 226, 282, 928, 939, and the I-35 business loop. There’s also a page for Business 61 in Maquoketa, which only exists on paper.
