Trod similar path as kids I brought my first motorbike brand new with possum skin money in 1978. The last pussuming I did was 1984. The shine had gone off it when the average price was $5-6 a skin and I was making much more gold dredging.
Working for myself chasing possums and gold for close on 50 years now has been a life, a lot of the time I wonder what I was doing this for there were some hard times. But look back I would not change a single thing, the hard times crazily are probably now my best memories.
I have not chased possums since 84 for many years I hardly saw one dead or alive on the roads. I think 1080 was keeping them under control. I’m now seeing them all the time again and what you have said confirms what I have been thinking some of them have got smart and are not taking the 1080 baits now. I hate 1080 sometime in the future I’m sure the experts will finally realise what an environmental disaster it has been dropping all over our back country.
