I collect travel mugs from everywhere I've been (and a few I've received as gifts).  I didn't start until high school and don't have a mug from everywhere I've been.  But I still have quite a large collection that I plan on adding to every time I go somewhere new.  



Going clockwise starting from the top right, the mugs are from: 1) the hoover dam - 2011, 2) NYC - 2005 3) San Fran - 2011 4) Gettysburg - 2009 5) Smoky Mountains 2011 6) Las Vegas 2011  7) Ecuador 2010  8) Busch Gardens 2007 (Sheikra roller coaster)  9) St. Louis 2012 10) Disney World 2012  11) Coca Cola Factory, GA - gift  12) Colorado 2011  13) Wisconsin  14) Chicago 15) Nashville 2012  16) Ft. Jackson 2012  17) Canada - gift
