Send answers for the May 2003 Where on Earth? contest,
which appears the print magazine, to Geotimes by May 26 (or postmarked by
this date). From those answers, Geotimes staff will draw the names of 10
people who will win Where on Earth? T-shirts. And from those 10 names, we
will draw the names of two people who will win a Brunton
compass.
