Member's Garden Party and Open Day at the National Botanical Garden of Wales. Well, we weren't going to miss that were we? So different from when we visited last. Very green and verdant and flowers blooming everywhere. BUT, as it was a special day, we didn't spend all our time above ground - no - we went on the trip underneath the mediterranean conservatory to see just how they deal with all the water, weather, electricity, waste, emergency lighting etc. Of course, as you can imagine these days a lot of it is done by computer!!
