Also, McCallister Technical Services on Sherman in the heart of CdA. They do custom controls & automation work. I stopped in and talked to them a month ago — it’s a fascinating company.

that sounds about right. I drop down to CDA about once a month, and to Sandpoint probably twice a month because I have to take my mom to Walmart. She’s 94 and loves to shop.
