As far as slinggolf goes, we did the Diana sized net on a stick in 2007

It did not work well lol
If you miss, you tend to end up halfway down the green.
And a hole that could have been below par often turns into double figures !

They take a different approach in guam.

And use a ground based target (pyrimidal I believe) that sits over the hole.
So you're basically rolling the ball in, which makes it easier to hit and less likely to carry on for miles if you miss.

Sling golf is quite well established in guam.
If you post on the worldwide Facebook slinging group they'll no doubt show you what they use.

But trust me, a target on a stick, is NOT the way to do it.

Facebook isn't really any more intrusive than any other social media.
It only knows what you tell it.

If you don't want someone to know something, don't post it.

It's a bit like these idiot celebrities who winge when their naughty pictures they've stored on a 'cloud' become public.
If you have to keep such things, never store it anywhere you don't have physical access to.
There are no clouds. Just storage facilities in countries that don't have privacy regulations.

But I digress.

I haven't heard from Roman in a while, might drop him a line and get the slinggolf info.
