Welcome from a fellow Texan!
Yep, Ken... looks like y'all are being overrun by us hicks from the sticks!
As to the locking gas cap... I am favoring the one at H2source.
Your wife will talk to you by Thanksgiving -- guaranteed -- if you buy her an H2 of her own!
Although, if she is REALLY ticked, it may be through a mediator or divorce attorney!
Enjoy!
