Weather Delays

We’d hoped to be working on the foundation walls today, but weather and schedules haven’t aligned, so we wait…it’s not that we’re overly anxious, but really—a few consecutive sunny, dry days really would be helpful for anyone working outside these days! Though after nearly two years of more drought than rain, we’re generally happy with and thankful for the rain—and there’s always next week, right? At least it’s cleaning the old tub we hauled out of a downtown Lanesboro building last week!

In the meantime, confirmation today that our local electric utility—Tri-County Cooperative—has us on their list for early next week to bury cable and install the site transformer. Initially this is critical for getting power to the site for construction, but long-term is our connection for the grid-tied solar photovoltaic system.
