>Nobody going for b,c,e,g,i,k, or l??

actually, b and k do have votes; let's consider whether the others are worthy..

c) thrapple.. supple.. probly not
e) I'm having problems *picturing "light, hoofed animals on a gravel track", much less hearing them
g) I'm sorry, this doesn't look like a real def'n to me (so this is probly it!)
i) "sound made by an outboard motor in brackish water" - points for imagination
l) one of those that almost looks *too real

even paring it down to these, I still can't decide -- but I've made a case for g and i, haven't I? \:\)

having typed all that, I guess I'll plump for i.
