Foreign tourists to be charged $10 "travel promotion fee" starting September 8

Directly from Gadling: Foreign tourists to be charged $10 "travel promotion fee" starting September 8. I am still trying to figure out, if this is a late April fools joke or an IQ test for tourists planning the travel to the US. BTW: a few years ago, the Balearic islands (Ibiza, Mallorca...) introduced a 1 Euro/person/day charge and within a few months they managed to reduce foreign tourists by more than 30 percent. So shortly afterwards they eliminated the charge again. Maybe they thought, that having tourists spending money there is not such a bad idea at all.
