Where did that come from?

I haven't submitted to any magazines this year and  have entered very few competitions. A variety of reasons - I didn't write anything for the first four months of the year; lack of time due to grandparenting duties; development of mistrust over the way poetry publishing works etc.
Anyhow, I entered the main Strokestown Poetry Prize and predictably got nowhere. I entered for all three categories for the Northampton Literary Prize - free verse, formal verse and humorous verse -  and got a big fat zero. I've entered  Poets meet Painters (results not yet announced) and the Pighog Press Satire (closing date put back to September)
So it was somewhat out of the blue, that I received an email today from Barton College in North Carolina, informing me "that the editors have chosen your poem "Two Graveyards in Picardy" to receive first prize for poetry in the 2011 issue of Crucible. Unfortunately, the issue has been delayed but is coming together quickly. Congratulations and thank you for submitting your work. A check for $150 will be sent to you soon."
Looking back, I find that I sent my submission on April 27th 2011, and naturally assumed it had ended up in the bin.
God, if you're up there, thank you.
