Well Keith , that was a delight! and all of the above comments about your brilliance are confirmed.
Your garden is beautiful too (love the viaduct shot with the purple and green in the background.
And, I watched your caving promo too. Did that long ago here in Colorado, where caves are mostly bone dry. Don't think I like the idea of going for a short 'dive' to clear an overhead, but , it was exciting to watch.
