Not at all, as a matter of fact I am not complaining, but I'm quite ready for spring now and those damn trees to start sucking some water out of the ground again!
Also, and this cannot be stressed enough in this thread, narrower tyres (read CX) really make it easier to go through the thick mud.
November to January for me, starting to get sick of it by now.
You need to know your routes though, some trails/footpaths are not worth it until springtime
