The Lost Treasure of Cabeza de Vaca
played
Nice journey along the Riverwalk. Definitely a must do -- but pick your times carefully, as crowds would make this one very tedious. I think our completion time was maybe on the order of 1.5 hours, though I wasn't watching specifically, as we occasionally strayed for an extra cache or two. It played without issues on my Samsung Galaxy S3, and zone navigation worked fine. I think only once did I have to try to get to a more accessible place to get the zone entry to occur. I did get the same question a couple of times as it seemed to pick up my movements as leaving and entering a zone. Nice combination of history with a few minor problems to solve.
