I disagree with "tough laws" when they inhibit the law abiding from getting their Rx. We're in essence trapped into 30 day trips or having the wife fly back every month which tends to make the concept of having a motor home moot. It took several months to find a Dr that would take her with an out of state license when we were in transition of moving.
Regarding faxing a letter from her Physician the point is also moot. A Pharmacy refused to fill the a Rx and the Dr (in good standing) was right across the street. The Pharmacist flatly stated "I don't fill these Px". Yes all perfectly legal.
