Here is some great Advice, Put everything in a Locker..cost .50. I carry my keys on a clip ring on my belt loop works perfect. I am not making any calls in line or on the coaster so no need for my phone . And trust me my job I am on call at all hours even when I am not on call so there is no reason take take a cell phone on a ride. I am truly sorry to hear about that loss of your keys I can imagine how bad that would ruin a trip much less a week or month..
