This morning, Michigan Stadium Aerials (www.michiganstadiumaerials.com) had updated pics of both the football scoreboard and the Player Development Center (PDC.) Short of being in AA, this has consistently been the best internetz source of high res, beautiful photos showing what is going on. The link is http://www.michiganstadiumaerials.com/construction-updates.html. They seem to be posting pics about once a week, and while there is no commentary, you can see more detail, plus get an aerial view, showing the entire football and basketball campus.
I did not make this headline up
