It seems the farther away you get from London, the quieter the celebrations were (that could also be a factor of population density as opposed to distance). Orkney’s festivities included school outings, a parade, a church service, and a community picnic.
I was going to take Scout to the community picnic in front of St Magnus Cathedral (Scout is always a hit at a picnic), and even went so far as to make Coronation Egg Salad Sandwiches (egg, mayo, curry powder, & mango chutney) and pack a bottle of upscale tonic water (mint & cucumber seemed appropriately royal).
It took a while to get to the cathedral, as there were a couple of cruise ships in town, and once we got there the lawn was pretty full of families picnicking. Instead we headed to the harbour, found a bench, and sat in the warm sunshine, admired the view, and said hello to passersby.
