RFLMAO, yeah, most times the Cannucks and other out of state winter snow birds vacate the area once the oven here in Phoenix begins to warm up.
:/ 40C and 70% Humidity, yeah that can get a bit muggy, still 120F and about 40-60% humidity during the summer monsoons in July and August here just about takes all energy out of your sails I'll say that.
OT
Leaving a mod /w tank in a hot car during summer is a bit dangerous and messy. Short hop in and out, I'd store the mod and tank upside down in a cup holder to keep leaking to a minimum. Longer than about 20 or so minutes, pocket the vape and just carry it with you, otherwise keep in a small ice chest with an ice pack (old construction worker technique) and in all instances, keep the unit out of direct sunlight.
