Had to resort to a brush mower
Since I had encountered mower issues from my last trip, we had to get back to the property to knock down the overgrowth that had taken over our driveways and walking trails. We travelled up on Thursday, and spent our time burning brush back near the clearing. We rented a brush mower for Friday from Scholze Ace Hardware, and used that along with the push mower to get things under control again.
We camped at the property in the pop-up camper and headed for home late Friday afternoon feeling good that we had things, vegetatively, under control again.
