Friday was ... interesting!
Its impossible to start and stick at this if you've got ego problems, I reckon. I could only squeeze in an hour between work and sundown down on a bushy grassy area near my house but found aiming uphill managed to catch my many many stray balls. Aiming at a tree knot helpes heaps too, since the branches toss my tennis balls back towards me.
Two balls still managed to mysteriously dissappear though.
I couldn't track them too far into the bush since snakes and spiders are quite annoying where I live.
I've been trying at about 15 paces away, since that's the furthest I can get with a proper target in view. Anyway, good news is that by the end of Friday I had a mistake area of about 4x4m, and since then its down to 2x1.5m!
I love this sport!
As for slinging style, does anyone else have a solely vertical overarm swing? Wristpower seems to be the key for me, since my shouldermuscels ain't too good from sports injuries.
