Merlin's Magic contains tea tree oil so I've sloshed a bit of it on the roof outside the study. To date have seen no new raccoon poop, but the spring is yet young and it's just a matter of time. The tea tree oil should discourage them.
Heat is kind in one specific way: it stops my hips aching. Put a Robax heat wrap round the lower back and got through my meditation session very well thank you. Second last one and not a minute too soon: uninspired is not the word for the way the seminar is conducted. Only plus is that one gets to talk to an absolute stranger and tell them things one has formerly kept for therapists, since no one else but the mythical Best Friend would be the slightest bit interested.
