I'm with Cachestacker, so I will not be joining the rush to get 31 (inflationary) souvies.
I may streak, but agree on the inflationary souvenirs. To me it kills the intent and purpose, to the degree they've half-way done another project. Should have done ONE if you successfully streaked each day in August. And of course, people could have done it any way and gotten ONE that way. Oh, well.
I just used one of the inflationary souvies to completes Cachestacers *Souvie challenge*. I was at 49 and it tipped me over to 50, the needed number.
As far as streaks, I have done over 100 days, which, yes start to get on ones nerves. If I have completed a *challenge cache*, I did use that cache as a find on a day I did not go out, or a day it was raining cats and dogs. I may have done that about 3 times because it is tough to complete some of the challenges sometimes.
I will admit tho, that in order to say one has truly completed a streak, they must physically get up and find a cache. I really do not know where/how challenge caches would fit into this scenario. What say the geo-community?
