World of Warcraft - Macro - Mount & Follow

I use this macro to mount and then follow pre-defined friends and family that I always group with.

/cleartarget
/use [nomounted,noflyable]Azure Water Strider;[nomounted,flyable]Winged Guardian
/tar [noexists][dead]Plank
/tar [noexists][dead]Ebony
/tar [noexists][dead]Palehoof
/in 1.8 /follow

The last line requires the Slash In addon.
