"I have crafted cryptic crosswords..." No Snarks (Yet): A Nonsense Rhyme

I have crafted
cryptic crosswords,

whistled “Dixie”
in the dark. 
Geese and ganders
I’ve steered sauce-wards.
Still, I've never
hunted snark.

Leading-edgy
with the Legos,
I’ve laid bricks to
fix my mark.
I’ve trekked T'erra
del Fuegos --
although not to
hunt the snark.

I’ve played Scrabble,
checkers, chess and
Go – in playpens,
parlors, parks.
Cheat at Go? Me?
Yes and no. But 
I have yet to
hunt for snarks. 

Have I Pit Bulls
bred with Pugs, be-
getting bites fa-a-a-ar
worse than barks?
Sure I have -- you
bet big bucks! Still,
I have never
hunted snarks.
