I called the Cove about needing the I68, and found that it's not really needed. The Mrs and I both have passorts, I have my Nexus, and she'll have hers hopefully soon after her interview on Monday.
I also paid my User Fee to CBP for having a private Vessel 30'+ in length and just received my decal this past weekend.
Upon return home Sunday, my uncle told me not even to call in my return, but I'm nervous that may not be 100% street legal, but I also don't know what # to call, I've tried calling Customs, and I can't find my way to a human being to get clairification.
