Jims's sons Johan and Adam step in to do the show today. We start with guest Matt Latham with Arborist on Demand to talk about the possibility of your trees freezing with this artic blast we’re expecting this week. Johan and Adam also take calls about a spray for sewer pipes, whether to turn off the breakers on an aerobic system, converting a generator, and more. They continue in the second hour on the phone lines with more home improvement advice. Stay safe and warm.
