Well, I'm thinking of an idea of an event where: In one particular town or city, someone (probably a kid) has lost something in the ocean, in a forest, in a cave, in an abandoned house, in a fountain. Basically something is lost somewhere and the kid wants it back badly, and whoever finds it for this kid gets a valuable reward. But who knows what waits along the journey towards this lost object and who knows if somebody already has it and wants to keep it?
They both sound cool, the storm and blizzard thing probably while the trainers are off trying to get something done but alas the weather. mother nature decided "Nope. nope, you are stuck."
The Festival/Tournament thing is interesting. What about a Festival that is about celebrating A town's history, a particular Hero? A hero who saved the town's people a long time ago. And at the end of all the celebrations of everyone making merry and chatting and dancing and all that good stuff. There is a tournament to crown the Town's Next Hero?
I was thinking about posting, but I think @josephb , I'll let you have the chance to post first, (if you want to), (let me know if you'd rather have me post first), since a bunch of things happened and I don't want you to have a ton of things to respond to at once.
