In Southern California , we have Santa Ana winds which tend to be very unpredictable. I have left in the morning(I live 15 miles from the coast) and had no wind with nice temperatures and when I get to the beach my phone rings . It is my wife telling me it is blowing a gale at my house, not a breath of wind on the beach! I tell her to meet me at my shop in Ventura , I am NOT fighting that wind!! I have had to get home several times with a mild offshore 5-10 MPH headwind can be common this time of the year and is challenging. I will usually ride these out unless I am not feeling 100% , then I call wifey and have her come get me. I am in it for the enjoyment not torture. Joe
