Ok, I'm glad I asked first, I didn't want to mow without permission (but for the record, if anyone wants to mow MY yard, you are more than welcome!!!).
As for the scary departure, it was a learning experience...I've got some bush flying experience in tailwheel aircraft...I've even landed a tailwheel on High Island before (which is another State of Michigan owned island, just to the north of N. Fox, and just west of Beaver Island), on the long sand bar on the northeast side of the island.
But, this was the first time for this aircraft (Cherokee 140/160) on tall grass. It had a much bigger effect than I thought. It also didn't help that there was a strong wind out of the east that kept us from the normal 25 departure. Eventually we got it dialed in though, and found the best technique, which included starting our run WESTBOUND in the cleared area on the southwest corner of the airfield, then doing a 180 to eastbound, crossing the west runway end eastbound at almost 20 mph.
