I’ve said it before, it’s my Hobbit name gleaned from a hobbit name generator (I forget the URL) A lot of people think it’s OverKILL for some reason …
Sky: The expanse of air over any given point on the earth; the upper atmosphere as seen from the earth’s surface.
Bum: One who is devoted to a particular activity or milieu: a beach bum.
SkyBum: One who has tasted flight, and has since walked the earth with eyes turned skyward, for there I have been, and there I long to return. (modified Leonardo Da Vinci quote)
Short answer: I freakin’ LOVE skydiving. 334 jumps and counting…
