You did very well winning the argument with the ATO Jilleroo. Keep pushing your Mum, If they get out of the habit of walking at that age, the ability to do it soon disappears. All the best to her, she sounds like she has a bit of ticker to her.
I got the concrete pads done for the grid today.
When checking the cows in the tin mine today, I was topping up the supplement in the feeder, I heard Bo starting to bark, grabbed the rifle and found her about 100m up in the scrub and sure enough she had a pig baled up. She stands off about 5metres, then when I fire the shot she flies straight in to it. She knows exactly what she is doing, the barking is to call me and we work as a team, she lets me fire the shot then moves in. If there are pigs anywhere around she will find them.
