VERY cool dream!!!

IMFL would be nice, but you could also try IMLP. It's late July, so you could do most of your training starting in January. OR.... you could just do an iron distance race that's not an M Dot race sometime else in the late summer/early fall (ahem... Redman in OKC... ).
There is also the Great Floridian (had a friend that did that one and he liked it), IMWI (in Madison in early Sept), Chesapeake Man in Maryland (Sept.29), or even the Tri One O One race in the Woodlands on Nov. 11 (101.06 mile race- a new series this year).
I totally understand if you have your heart set on an M Dot, but there are LOTS of other options for iron distance if you can't get into an M Dot.

Awesome, dream!!!!
