Had the same thing happen to me last summer in ely with my boat key. Day 2 of a 5 day trip to ely with the boat. Looked around for hours tore the truck, camper, boat apart, went through all my clothes, asked other campers if they had seen it, asked the front desk if any one turned it in. After four hours of looking for it I went into ely to find a merc dealer. But it was July 3rd, and of course he was out fishing. So i returned to the campground with thoughts of fishing from shore for the rest of the weekend. Then the wife chimes in " let me help you find if". Thats after 4 hours of searching and a trip to ely. She starts with the truck. She opens the glove compartment.."here it is". In my truck the only reason for a glove compartment is for the owners manual. She had put it in there that morning and didn't rember. I have defined this event as my most frustrating fishing event ever. Needles to say she let me go out for the rest of the day to work of the frustration.
