Nuf,
You need to find a farmer with one of them new-fangled wind turbines on his land . Then all you have to do is go there on a windy day , when the turbine is spinning like buggery , and blast away at the blade tip when it comes past , doing about 200 miles per hour !! Think about it ! That blade tip will be rising , in an arc, at speed , just like a pheasant who's swallowed 4-Star !! You and your mates could have some rare fun.
Imagine trying to hit the bugger when it reaches the top of the circle and the turbine is 400 feet high? Think of the money you'd save on clays! ?
If you've got a couple of bazookas and a Gatling Gun, you could have even more fun !! There's nothing like a moving target to make it exciting as you blast away ! The wind turbines are useless anyway , so no-one will notice the difference if they get a bit frayed around the tips.
Whatever you do, don't go there if the wind speed is below 12 mph; the blades will be on stop....... and it won't be a challenge to hit them then!!
