Yep Mate, I was also thinkin' maybe some barbed wire for the USB extension but the General Store sold out
Don't worry about any sheep eating the grass. On Saturday, next-doors 3 horses are coming in for a week of feeding on my backyard overgrowth! Then they attack the paddocks!!
p.s. Speaking of Aussie enginuity I was thinking about a Holden V8 for the tracking but I can't get one to idle in Sidereal Time, only Lunar and Solar Time LOL!
