Did this "brelly" in a Mystery also JAMP124. Too big for me to handle. I was always more comfortable in a beach chair with a little umbrella which clamped onto the back of the chair. At least my back was comfy.
Not a fan of beach umbrellas...never felt like dragging them up and down the beach while looking for a spot to bake. Always ended up just trying to keep my eye out for my two kids while they were in the water. Couldn't lie down or read a book. Don't live near a beach now, and I don't miss it.
Same here theorangutans. This took me a long time to solve. Long...like the rain here in Oregon. Day, after day, after day. I think my fingers are starting to get moldy. :(
