If you transfer to a Continental puddle-jumper at the Houston airport anytime soon, be prepared to undertake an epic quest! (Here's a map of the airport for reference.) My flight from Detroit arrived at gate C-43, and my next flight departed from A-7. Now, C-43 is pretty near the center of the airport (in the lower-middle on that map). Following banners with directions through construction in the center of the airport, I was eventually led to the TerminaLink shuttle train station next to the north concourse. The trains there ran to Terminals B, D, and E, but a sign said that I should go to Terminal B on my way to A.
The train dropped me off near the center of Terminal B, from which I proceeded to take a couple of not-obvious turns to reach a long hallway on my way to Gate B-84T. It turns out that "B-84" is actually a whole big set of gates: once you finally reach the B-80's area, you go around another corner and down another hallway and a flight of stairs to an independent spur jutting off to the side. In the middle of all the other Gate B-84's you find B-84T, which turns out to be a door that takes you to a shuttle bus stop on the runway. The bus winds its way around the roads and runways of the secure area (occasionally waiting for planes to pass) until it finally drops you off at gate A-2. From there, it's a relatively easy shot over to A-7 (though I was momentarily worried when A-7 stopped being listed on the overhead signs as I got close).
I fully expected that before being allowed to board I would have to correctly answer three subtle riddles and then prove my purity of heart to the magical dwarf who guarded the only key to the jetway. Fortunately, they were content to simply tear the corner off my boarding pass instead.
