its not gone, right you need to call around tree surgeons, asking if they would climb tree to retrieve your machine for payment. tree workers are rock climbers, use same gear an harness units. and is your best bet.
maybe hint it could be good for apprenatices if they have any to learn to climb and at same time gain your machine back. dont be disheartened buddy we all been in the tops of tree before
Man up get your boots on we came from apes, stop being a big girls blouse and get climbing, find a few brushes at home take heads off gafer tape, rope to put round your neck incase you fall. Title should have been got it stuck not lost, grow a pair, come on man, bring back national service
