Hi, Ivan:<br /><br />You more-or-less edited this one yourself. I had the same&nbsp;ideas and misgivings as you. I hope I've&nbsp;helped sort them out.<br /><br />Back to the heat for us. My wife's gone to Toronto for the day. However, I have a friend with a pool, so guess where I'll be? (I often say this and then never go.)<br /><br />BFN - George
