Small world isn't it? My husband is from San Antonio. I always claim Austin as my Texas home since I spent most of my Texas years there - from college in 1969 to 1991 when we moved to the Pacific NW.
I must admit I am going to have a few eats not on FTS while there in March since it is only a once-a-year trip: in Austin, migas at Trudy's, Tex-Mex at Matt's El Rancho, a burger at Dan's, and fried mushrooms at Mama's in San Antonio! But we'll be very active while there, what with the grandson and all, and like I said, it is only once a year, and is food we can't get up here (thank goodness!).
I think doing that will actually make me appreciate how I feel on FTS and I will look forward to getting back to it when we get home. I actually fried up some jicama this morning (at 4:30 a.m.!!!) to have on hand (per Doug's suggestion). That says how dedicated I really am this time, and perhaps I won't go too crazy on our trip because of how good I will definitely be feeling by then.
