Hmm I don't know if it's dangerous(?) it's just like rambling or hiking, I don't think it's even as dangerous as aa like urban exploration or whatever.
I'm not sure I need to gamify going for a nice walk, but I also think it's a bit curious. Maybe they will send you to somewhere you wouldn't normally do and see things you wouldn't normally see. I think it makes sense to tie it in with Atlas Obscura. I'm not sure I need the Treasure, a simple 'look at this amazing view' would suffice for me:)
