To prevent forest fires many areas no longer permit campfires or cook fires built on the ground. Instead only a commercial cook stove is permitted. If you become destitute or otherwise find yourself in an emergency situation, violation of such a regulation may not be tolerated by well kept government officials who could care less about whether their hard boiled antics may be responsible for the skyrocket increase in arson and who will put you behind bars and feed you jail house food without a second thought.
If you have built a cook fire on the ground and find yourself in route to jail, just write a letter to your congressman and petition the government to provide anyone who is in need of cooking the food they have to eat or boiling water they have to drink, under any circumstance of desperation, with a free commercial cook stove and fuel for its operation versus locking offenders up in jail.
If you must cook the food you need to eat or boil the water you need to drink in absence of government understanding and assistance then a stealthy and disposable alcohol fuel stove may help keep you out of jail.
