I couldn't wait, so I (also) googled arm/leg restraints this morning. Besides the medical and law enforcement applications, and skipping past the sexual bondge types, I did find another valid use for them: race cars have them. And dune buggies, ATVs (quads) and those little Rhino and Razr-things have them, too.

It's been said in these threads that Alanna's family had recently been camping. If this is true, maybe they "camp" like we do: we're all about our "toys" and not camping at all, really. We're desert rats here in Cali. We've got motorhomes and trailers full of toys instead of tents and fishing poles. Camping = quads and buggies and dunes; there's even a Razr in the family (much to my dismay). (Google Glamis Dunes) This means that although I didn't know it, I must own some number of "arm/leg restraints" myself
. We just call them "cages" or "nets" or "roll bars" instead.
Could it be that simple, Alanna's family owns/rides ATVs, or races?
