The suggestion on using air conditioning included a little common sense BK. No one would suggest leaving a running vehicle unattended in a shady looking area, large busy suburb, inner city neighborhood, or large mall parking lot. Stopping off in Galena Illinois (population 3460) and having a bite to eat at Happy Joes Pizza Parlor in broad daylight is unlikely to result in a smash and grab/theft in the 30 minutes it takes to eat.
A large truck is probably a little more forgiving with airflow and heat than a car that can get to 140F within a short period of time. I have no clue how many reptiles Pam owns. If Pam has the ability to carry along enough cool packs for a couple days to cool off all of her individual containers and has the ability to place and remove the cool packs back and forth between stops, then that may be a better option for Pam to consider.
You can bet that when I relocate to Texas and take along all of my reptiles, I will be opting for the air conditioning and decent looking restaurant in a smaller quiet city rather than trying to individually cool off several dozen containers several times a day over a 2-3 day period. I am not saying that there is no crime in smaller well-groomed areas, just would place money on the fact that a smash and grab/theft in broad daylight in a city like Galena Illinois will not take place in the 30 minutes it takes to eat my lunch.
While I do not typically advocate leaving a running car (even locked) unattended, Pam’s situation is not an every day event. I do not think that this suggestion is totally outlandish given the fact that Today’s MSNBC did an article on pet safety in January and included this recommendation:: “Carry two car keys with you, so if you have to leave your dog in the car for even a few minutes, you can leave the engine running and the air conditioning on, with your dog inside and the doors locked. Take the second key with you so you can open the door when you return.”
(I must point out that I do not advocate allowing a dog to stay in a locked running car unless the dog is restrained with a seatbelt (yes they make them for dogs), as the dog could potentially open a window by stepping on a power window lock.)
My point in this is that this can be a valid option to someone traveling across state with a vehicle full of reptiles if common sense is used (choose location wisely, short period of time, restaurant with plenty of windows, daylight) and other options are not feasible.
