The No Campfires may be by law... In some conditions the government puts out a burn ban and that includes (in some areas) campfires...
I have a propane campfire that is exempt from those burn bans. Even used it a few times.
ICE CREAM.. I do know some companies whip a lot of air in to the mix
Schwan's is heavier (usually) than most "Store bought"
And a friend of mine was named Jack.. but folks called him Henry... WHY.
Well he used to work for a man named Henry who started a company (Henry's Ice Cream) as a "Jack of many trades" He pedaled the product all over the neighborhood (Bicycle delivery boy) Curb hop. General go-fer.. Saved his tips and income and when Henry Retired... Bought the place... Made some very fine ice cream.
Also did molds. and bricks with a design that ran all the way through the brick (Example you got a brick with a christmas tree stenciled on. only you sliced it there was still a tree "Stenciled" it ran through)
Shipped via Greyhound package express all over the country.
THat was good ice cream.. Last time I passed though he'd retired and his sons had no interest so.. Closed.
