Any chance that mole killer is for rent?
I (well I should say we...no scratch that...My wife) has a female Australian Terrier that is a killing machine. She's funny too, she'll attack wasps like crazy and kill them without getting bit...but she has no interest in a spider walking across the floor. I've seen her grab snakes we didn't even see off the side of a walking path and beat them to death...then just continue walking away like nothing happened. She's had limited success with the mice and moles that live in the evergreen bushes in our backyard though...not for a lack of effort though. She has the heart, just needs some tutelage I think.
Shop looks great! Bet you can't wait for it to be done.
