Hello Geocachers! My brother passed away several years ago and I've been struggling with what to do with his inherited HotWheels collection. It's massive. I thought it would be fun to set some in a geocache for kiddos (of all ages) to find/keep. I'd just keep filling the cache as the HotWheels get picked up. That would really honor his memory and allow for others to enjoy the cars he loved collecting. Since I've never geocached, I do not know if this would be an appropriate/welcome thing for me to do in the caching community... any feedback/advice on this idea or any tips on how I should get started? I'm thinking of ordering the clear ammo cache as it looks like it would hold at least 5 cars at a time.
