Hi Mamabear2,

Those things can be loud! Especially right behind you.

Ease of use, hey kids love them.

I concur with your thoughts on putting them in the vehicles. Potential concerns (maybe not so much up "nawth" in your neck of the woods, but it hits home here in MIA) is the heat in a car. They are pressurized, reckon that they would be safe enough kept in the glove box or similar place. Just like the phone, finding it after the accident could be problematic. Not so problematic as not having it at all though.

We looked at these in Wally World" several weeks ago (think that most larger boating stores will have them as well).

You are right, perhaps it's time to add one per vehicle. Possibly even a spare canister as well. Good thinking.

Have a great weekend!.
