Oh, yeah winter again...
Stages was no problem (So, there is a running route signed- therefore i MUST make a jogwalk-tour, could say my first run since august - oh,yeah i'm in a desastrous form .
Finally calculating - take shortcut to cache, that looks suspicious, short check - then thinking 'Are my calculations correct?'- Oh,no another 50m in this slippery terrain.
Searching, finding something,but not the cache..
Check calculation again: AArgh! mixed Cache with the ideal entrypoint, so first location was right...
Slippin' and slidin' back - turn on the light,looking 1m near the first check ... and found the cache.
Maybe sometimes thinking less,and trust your own solutions works better..
