As you probably inferred from my U is for Utah post, we made it here!
Mr Jummy enjoyed the flight over immensely and liked looking out the window at all of the clouds.
He was not, however, impressed with how the border agents acted once we got into Houston. "Oh crap," is not something you want the agent to say after they scan your passport. We got "escorted" all over (because we are renegades apparently), then they dragged Martijn off into a holding room and sent me off to wait alone by the escalators. Not ONCE did they tell us what was up, other than his passport had been flagged. We still do't know. I was really grateful that I booked the earlier flight out of Amsterdam that gave us the 7.5 hour layover in Houston instead of the later one that would've only given us an hour... because we would've missed our connection!
Anyhow, all is well that ends well... and we probably will try to avoid flying through Houston again in the future since they seem to have it in for Martijn (this wasn't his first run-in with the immigration "officials" there).
