Glad you and Jen are coming to Getaway this year, Art.    Last year we had at least 6 people from NC (3 different cars) at Getaway, and I hitched a ride back with Dani and Abby (then took Amtrak from Raleigh to Greensboro for under $11). I'm hoping there will be someone driving back this year who has room for another rider, but if not, the train (or maybe Craigslist rideshare) is an option.   

BTW and FWIW, my Southwest airfare of $320 is for two one-way tickets, one from Portland to Baltimore/DC and one from Raleigh/Durham to Portland.    Two one-way tickets are as cheap as one round-trip ticket.
I really love Southwest's policy of not charging fees for changing flights.   If you need to cancel one flight, what you paid for the ticket can be applied to any other ticket within one year.      So if I have the chance to get a free stand-by ticket to the Baltimore/DC area via a friend (which is a possibility), I can apply my $153 to some other flight that I take before June 13 next year.
