More likely than not, our 2009 visit was our last, at least until I retire.
For over 5 years now we've been planning a transfer to New Hampshire. It looks like it might finally happen this coming March/April/May. My retirement window is May 2013 (eligible) to May 2020 (mandatory).
We'll be taking regular trips back home to Arkansas, but I don't know if we'll be able to work in SDC trips during that time. I certainly hope so: I'd love to have a big family gathering with my mother, sister, niece, nephew, and any kiddos and spouses who can come. The whole family has great SDC memories, so it would be a great reunion.
