In those days the shore lunch went into the boat in two parts. There was the sturdy wooden box, painted forest green, with the hinged top, the hook-and-eye latch, and the rope handles on both ends. This went in the stern, next to where the guide sat, and it held the eating utensils, the cans of pork-and-beans, the bricks of lard, the breading and seasonings for the fish—everything except the cookware. That went into a burlap sack, which was tucked up under the bow.

The nation's first park announced a ban on felt sole wading boots March 8. It's rubber only when fishing season opens May 26.

"People who are coming to Yellowstone National Park to fish and boat care about park resources and this is just another way to help manage invasive species," says Vicki Regula, Yellowstone National Park public affairs assistant. "That's a definite high priority in Yellowstone National Park because of all the ecological and economical impacts invasives can have on waterways."
