DH loads the podcast onto his phone which can be plugged into the car. There are now three different podcasts I listen to - You Bet Your Garden, The Dirt Doctor and now ATP. Especially good for longer car trips. I did check out some of the pics online after hearing about the herb spiral.
I had some concrete chunks that I used to shore up a small corner of one of my garden beds to prevent some downhill erosion. My wooded back yard slopes down to a wetlands where a once-larger creek flows. Picturesque but home to tons of poison ivy and mosquitoes.
