Group on the hill

I had a choice of blips today. Yesterday was my daughter's birthday and I got my friend Gill to make a coffee cake as they are delicious but R and I went to a party last night so we are going to eat the cake today. A group of people appeared on the hill between the house and the sea. Who are they? They look like ramblers but then stopped and seem to be getting a lecture. Could be geologists. It would be nice if they just came up to the house and said who they were.
Weather mixed again snow and hailstones in the morning but the sun is peeping through now and then but still cold.
