We have a much warmer February here.  We don't have a professional gardener's help.  We  have to take care of it from time to time.  So we did little by little, we thought.  But our physical strengths are very limited which is worse than last year. 
When we use the muscles which we usually don't use, then we will get trouble. Sigh....
Strange pains are everywhere, so we haven't ridden for three days.... 

But we will sure ride tomorrow no matter what!
