Been watching a few other resorts installing lifts. Sunday river recently posted a pic of concrete going in for the summit terminal as well, so it would appear they are on pace with Blue, without knowing the status of tower footings.
i would think they need to be hitting the concrete pretty hard over the next 2 weeks. We have had issues with concrete this year, so Blue might be too, but its a size-able job, so it probably puts them pretty high on the suppliers list.
