Here in West Michigan we have exceeded the 100 inch mark of snow already for the season so I can sympathize abit with you New Englanders. I have been doing a cache a day since the beginning of October and it's starting to get to be slim pickin's on the number of caches that are actually "findable". Did a PQ for caches with the winter attribute but even alot of those are not findable due to level of snow cover, snow plow banks, and/or no safe parking anywhere near the cache.
I've gotten use to climbing 4-5 foot plow banks and wading through knee and thigh high drifts. However, if I see the cache area is completely buried, I just nope it out of there. I hate just blindly digging trying to find a cache, better to leave it for the warmer months.
Recently did another PQ just to show caches that have been found in the last week. Figure I'll have a better chance at finding those.
Good luck and stay safe!
