It seems to store better in the attached garage
than my wood floor shed. Mid-Atlantic
Can be very humid though some are much
worse. Paper charcoal bag is meant to breathe
to help equalize the moisture content.
Have had many bags older than a year burn
just fine. Had some brand new stuff burn like crap.
Went back to the store andnsaw the bulk of it
being stores outside in the open garden center
not in the roofed part. Stopped buying
from that Lowes.
