11. Pennsylvania has some unusual laws which affect explosives
In Pennsylvania, a law has been on the books since colonial days regarding the celebration of weddings. It is against the law to fire a gun, a cannon, or cause any other form of explosion at a wedding, either in celebration or otherwise. By the way, ministers are not allowed to go forward with a wedding ceremony if the groom is in their opinion drunk. A more recent Pennsylvania law allows merchants of the state to sell fireworks, but not to residents of the Commonwealth of Pennsylvania. Another law still in effect requires motorists to stop at intervals of one mile when on rural roads, fire signal flares, and wait ten minutes for livestock along the road ahead to be cleared out of the way.
If the same motorist, or any other driving along the road, saw a horse or horses coming towards him he not only had to yield the right of way but disguise his vehicle with a tarp or other cloth which concealed it completely in a manner which allowed it to blend with the environment. Pennsylvania is one of several states which outlaws the catching of fish using only the hands (Indiana is another). However, Pennsylvania also outlaws the use of dynamite or other submerged explosives to catch fish. The use of explosives in fishing often led to many dead fish of all sizes, those undesired left in the water, and thus the state took action against the depth-bombers.
