I have 4 empty propane grill tanks that are the old style that cannot be filled anymore. yard wants a big hole cut in the side of them. Way too much work for way too little money!
Hoping to take them shooting one day (after filling with water to displace any residual gas) and make swiss cheese out of them. Hopefully the yard will take them if you can see clean through em!
Watch out for ricochet's. Might want to duck for the shrapnel too.
