This Week's Problem: "I travel for work, stay in a lot of hotels and always seem to end up with 3,428 hotel key cards at the end of the year. 1. Is there something I can do with these (eco-wise)? 2. Can anyone come up with a better idea for frequent travelers' room keys?"
Jason C. say, "Eco-wise you should drop them at the front desk, so they can reuse them. However they could be made into guitar picks."
Thanks to Jason for his response to This Week's Problem!
