Masts get stuck in Corpus all the time. The sand is hard as a rock so people don't think it'll be an issue, I guess. I've started keeping a roll of packing tape in the gear box and I tape over the joint between the mast halves religiously. No problems since then.
I have a friend who windsurfed in OKC for years back in the 1970s. Definitely plenty of wind there. I saw Hefner Lake when we were there and it looked pretty nice. Then again, so did El Reno that day.
We finally broke down and bought a Yagi antenna for the phone and without pointing it we've gotten service in two different places we couldn't get service before. I suspect it'll work well in Corpus because we were almost kind of getting service already. Personally, I liked it back when phones didn't work out there at all.
Oh, and I suggest we get Carey to do the showing and teaching. He has this "how hard can it be?" attitude (my response is, "Impossible--that's how hard it can be"). I taught him how to windsurf originally, and he's passed me way by but is nice about sharing. He taught me how to clew-first waterstart and I've got the typical girly spatial abilities, i.e., none. Actually, that may be a miracle of the same magnitude as the duck jibe.
This last trip was fin-first sailing--it's a long walk in knee-deep water from the shore to the dropoff at Bird Island. He fin-firsts his way out there routinely now. I've had some impressive fin-first trips, but I've very wind-direction dependent, plus it's surprisingly tiring. I'm sure holding my breath because I'm concentrating so hard doesn't help. So I stomp through the water, dragging my equipment like everybody else, while he glides by.
And by the way, you'll probably need a weed fin at Bird. I'm not sure when weed season is, but I've needed one whenever I've been. They're the long stringy kind that won't suck you under and drown you, but they WILL slow you down. There's a concessionaire there who rents and sells them, but you might keep your eye out for a cheap one while you're in Hatteras.
Hope you have fun during your two weeks there. We're leaving Chicago shortly for Denver and will keep an eye on McConaughy because we'll be passing by there. But we're trying to beat the cold weather for biking at Breckenridge and Copper. Decisions, decisions.
