Unique Interests

[cjsmith]

Meme stolen from firecat

Items from my interest list that no one else has in their interest lists:

embedded software (I'm mildly surprised no one else lists this)
n47490 (the plane I took my checkride in, and have since sold - not at all surprised it's unique)
pitts (the aerobatic biplane - I'm not very surprised at the uniqueness of this one)
square dance calling (I'd be stunned if another caller were on LJ)
taildraggers (with so many flyers around, the uniqueness of this is odd)

I think perhaps my interest list is too short. I can think of a few things to add, and some of them might well be unique in the LJ universe.
