Agreed. It's an open, municipal, public use airport. I looked around
a bit on the city's web site. According to the "Official Schedule of
Rates and Fees" at
http://www.ci.scottsdale.az.us/ratesandfees/data.asp:

Overnight parking fees assessed to transient aircraft
Rate/Fee Amount: $5.00 per night
Authority: City Code; Ch 5; Article I; Sec 5-116

My guess is that if you ask for progressive taxi instructions to
transient parking, you can get away with not paying the $50 ramp fee
(!!??) that Scottsdale Air Center is charging. Lots of interesting
comments about that on Airnav. I did my primary training out of
Southwest Flight Center at SDL about five years ago. They were very
friendly and I'd bet they would be happy to sell you fuel off their
truck at transient parking. They're in the "Aviation Business Center"
next to the terminal building. They're probably getting the going rate
at SDL of ~$5/gal. though.

I'd maybe call up Mr. Read, Assistant Aviation Director, and find out
the real story with the $50 fee.
