Setting aside the propriety of filling in the exchange post-contest,
buck.com is an unreliable source for grid info.  I've tried several times to
get it to show my correct grid (GN37).  It took the lat/long info, but shows
a grid reference (GO62er) almost 700km away.  That would have me bobbing
around out in the ocean.
