Cartons, cigarette butts, and other trash do not add to your enjoyment
of the park. You can easily dispose of these so that they cannot become
obnoxious to you and those who come after you. With the number of
visitors increasing each year, you can help protect and preserve the
natural scene by placing all paper and other refuse in containers
provided for this purpose and by refraining from picking or breaking
flowers, plants, and natural specimens. _Won't you do your share?_ THANK
YOU.
