OK, so if you have a field or wide open field........
Put out a 5 gallon pail. What you are gonna do is fly low and fast, then pitch up and "toss" your ordinance (golf balls work great) on the pull up. Try and toss into the bucket. Get your buddies involved - each with different colored or marked "ordinance". It's not easy due to the variables - speed, height, wind, where to start pull up, acceleration of pull up. Initially it may be whoever gets closest, then eventually someone is gonna lock it in and start putting the balls into the bucket. Soon wagers will be out there and the pressure will be on....
Addictive and a lot of fun! Enjoy
