I have four windsocks leftover from what I had ordered about 9 months ago...One sock was left in the clubhouse, but I'm not sure if that one is still available. I was going to return the four I have due to the complaints received about the sock showing conditions were soarable when infact they were not, but I'm not. We can live with them in my mind, or at least use them through the winter and spring...
With regard to filling the flag pole with concrete or whatever, that is a bad idea...that pole needs to be raised and lowered and is heavy enough as it is. If it got bent due to the recent winds, then lets simply replace it like for like...no concrete or rebar...bad idea.
So, if we need a replacement sock by the weekend, let me know and I'll leave what I have left on my front porch in San Mateo...someone from the club can pick them up and install a replacement. The sock should be attached with a combination of clothesline-type material threaded through the loopholes and sock frame and some zipties, too...not black tape like we've done in the past...I'll be heading to MN early tomorrow morning, if a windsock is needed, give me a call, at 650-863-1298.
