The Hamboree committee and board would like to extend
a Special thanks to Henry WD0DMO #1526 for taking the
KS/MO/NE/SD/WI/IA/IL/MN Hamboree mailing lists.
Thanks to this effort the flier was spread all around the region.

A bit of trivia.
A few people have asked what kind of area does 3900 Club cover? So I ran this table on the active members of the club as of 2/26/18 and this is what I come up with. See table to right.
