We made it back from our trip to Guaymas Mexico without much incident. The only exciting thing that happened during the flight, which happened to us last time we went to Mexico as well, was that we had a hard time reaching ATC/FSS while trying to re-enter the US. We climbed up from 9,500 to 11,500 feet and finally reached FSS to relay for us and get us a squawk when we were about 2 miles from the boarder near KPRS. It really surprises me they dont have a radio tower closer to the boarder. The closest one was 40 miles from the boarder so trying to hail someone at a reasonable distance out was no joy.
Our experience at the Guaymas airport was much better this time since we knew what to expect. Plus the agents there spoke a little English this time which helped a lot. I made 3 copies of all paper work - aircraft registration, airworthiness, pilots license, etc and stuck them in a folder. The Customs process in Guaymas seems a little unorganized as you bounce from area to area and paying fees and doing paper work. Overall, it was a good experience.
We paid approximately the following costs:
$130 for a multi entry permit (good for the airplane for 1 year)
$30 for 4 days of parking
$7 for landing fee
$24 per person (not pilot/crew) entry visas
$5 per person exit visa (non pilot/crew)
+tip for the nice guys who helped with baggage.
