Word to the wise - avoid clearing Customs in Syracuse, NY.

You must talk to US Customs before leaving Canada, to get permission to clear Customs at their facility. The official info published in the FAA Airport and Facilities Directory for Syracuse says that they only accept such phone calls starting at 0800. So, I called at 0800, and they tell me to call back at 0830. I call at 0830, and they tell me that there won't be any Customs officers on duty until 0900, and that I must speak with a Customs officer to get permission to come there. Arrgh!!

So, here I sit, watching the clock slowly spin towards 0900.
