Now that's an interesting point, about whether the law clarification about "traveling" allows you to carry in your car, even when your car is on someone else's property where they have posted 30.06 in the parking area. I would be very interested in a discussion of this, perhaps under a different topic.

However, in the case of Fiesta Texas, 46.035 applies:

(f) In this section:
(1) "Amusement park" means a permanent indoor or
outdoor facility or park where amusement rides are available for
use by the public that is located in a county with a population of
more than one million, encompasses at least 75 acres in surface
area, is enclosed with access only through controlled entries, is
open for operation more than 120 days in each calendar year, and has
security guards on the premises at all times. The term does not
include any public or private driveway, street, sidewalk or
walkway, parking lot, parking garage, or other parking area.

So it looks like you can drive in through the booths with the 30.06 sign and leave the gun in the car after you park.

I wonder what the value in the distinction of an "Amusement park" is anyway, since it seems that any private business can put up a 30.06 sign and keep CHL holders out.
