Dear Cecil Lee, thanks for the frank and clear advice. I feel like being thrown back on a schoolbench ! FLUNKED ! That is cross-cultural educational pain I have to go through. Tough luck. But if it is so obvious, why didn?t they tell me months before ??? I guess round edges could change a bit. But for now I am at least relieved that it is not just an excuse to get out of it. There were designs in Oct last year that led to the decision. I?ll post a few of them. So even if houses are far from each other, porcupines will get them , hugh ? Thanks ! Alex
