Solve the puzzle to get the true cache coordinates. There is no reason to try to access the posted coordinates. Two of the caches in this series are not winter friendly (they are the two regular-sized caches) but all of the other caches should be.
It’s wintertime and there are never enough winter-friendly caches. So here is a geoart – something to help feed your winter caching fix. I hope it’s not wrong to say that the roads here appear reasonably well-maintained, but the ditches could end up with deep snow so be prepared for that. I had no trouble with my car, so low profile tires should be just fine. All caches are hidden in the road allowance and should be above the snowline. Please be sure to pull over to the side of the road and respect local traffic. Have fun!
