Hey -- thanks guys and gals! It was a real surprize to receive so many Birthday wishes -- definately a warm fuzzy feeling. I enjoy this "group" so much and I'm looking forward to my second half century including lots more aquatic gardening -- which will mean continuing to ask for help and advice from all the great people who contribute here. I'm having a great day and the weather couldn't be more perfect. Thanks again! :) Olga in Vancouver
