Tanky,

All states but two, Wisconcin and Illinois have concealed carry laws. Vermont does not require a permit, anyone can carry concealed in Vermont. Some states have more liberal reciprocity laws. For example there are many states that will recognize a CCW permit from any issuing state. Others will recognize a permit from any state that has requirements equivalent or more restrictive than their own. There are a handful of states that will not recognize a CCW permit from any other state such as California and New York.
