I just wanted to let players know, two new LARGE challenges went up today, one yesterday actually. I am rather proud of both of them. I will not say where they are, but here are two good rather eclectic hints:
1. One could be in a city, or out in the sticks, the other is likely an urban find.
2. take your iOS device to work or school today and you may find one or both.
Both are dangerous. Level 5 and up.
