Previously, if you obtained a Florida or Utah permit, you acquired quite a few
states where you could carry legally, but in 2007, the Tennessee permit became
valid in all the same states as the Florida permit, and the Utah permit only
adds the additional state of Washington, but if you live in a another state
besides Tennessee, obtaining Utah or Florida permit may still be a good idea.

Maine and Massachusetts do not recognize other states' permits, but issue
non-resident permits, so they may be worth considering if you travel to 
those states.  Be sure to check all states' requirements before applying.

In 2007, Nevada began recognizing a few other states' permits (TN included)
and you can still apply for a non-resident Nevada permit.  There are some 
differences of opinion on Nevada reciprocity requirements, so if you travel
there using your home state permit, I recommend you check with the local PD.
