Notice that she has been claiming she has a phobia about air travel, and yet the letter has her traveling across the country.
Well the letter says she was on vacation in the Mid-Alantic. What we need to know now is what was her mode of travel? She could gone by land. But if she went by plane then she has really dug a hole for herself if it can be proven. And if she was on a plane then the government could find that out in mere minutes.
High speed rail... oh, wait...how is that less enclosed than a plane. She said confined spaces bother her.
