Great advice from all here, for me it all started with buying a single cigar....
I bought my first (of many) humidors after the FIL brought 2 boxes of Monte #4's from the ISOM.... it was a 60.
Bought a 100, was gifted a 40, bought a 300, then the first cooler, picked up a second and yesterday a third....
I'm looking at a vino and getting rid of the wood humidors.
My suggestion is to pick up a smaller cooler, you can always use it for beer if you don't fall off the slope, and if you do, you can still use it for beer.
Relax and enjoy the ride
