Appreciate it. Thanks for the concern. I will take your advice under consideration. My recommendation was spot on however. Reason? I live here. I know the weather. I know the area he lives in. I know the altitude of Snoqualmie and I knew the weather on the day he wrote the post. He also stated he would be moving the tank on Sept 7th. Which is the time I may be in his back yard so to speak, bow hunting as I've done in that area since the early 70's. Although we usually have was is typically called an "Indian" Summer, this year has been very different. Colder. Wetter. (is that a word? wetter?) Anyway, I had a slight advantage knowing the weather & area and the advice I gave was based on that knowledge not on assumptions. Again. Thanks for your concern...
