I settled early, for just going for silver. As a few others have said above, I need to keep unfound localish caches, available for further challenges/bad weather days etc etc.
I also don't travel, unless I really want to be somewhere, not just for a day of long driving, and madly caching in the hours available. That's why I'd prefer notification of all the challenges, in advance, so that I could research, book a holiday somewhere, enjoy the holiday and the caching!
Looking forward to seeing what's revealed today, and then at least I can plan for May's caching!
