Had more than normal custys ask me in the last few weeks. Most seem to think winter is November to February which worries me about their intelligence since winter is actually a month later but back to the topic, had a few last year.... About 3 stopped and this year so far on about 6. Pity since if I find someone to replace them they are dropped. But I know whats going to happen... I will move them march and charge them double for a first clean.
