I made this macro late in my Booterang career, but I found it useful nonetheless.
/target Disobedient Dragonmaw Peon
/cast [target=target,exists] Booterang
If you leave the icon a big red ?, this will give you 2 nice indicators when a Peon you can boot is in range. It will change to the Booterang icon when you click it and one is nearby and it will also target him for you. You may be out of range for the boot and may need to circle a bit to find him, but it makes hunting them down so much easier. =) Enjoy!
