Flashing lights. I have to try that now.
Years ago me and my sister walked through our newly built town centre together. They had installed bright white stone on the ground and both of us couldn’t stop sneezing (sunny day, stone reflects sun back up). It’s not as shiny now it’s not new but I hate walking through that area to this day.
Years ago around Swanage and the surrounding areas there was low humming, I’m thinking early 2000’s. It was speculated it was caused by oil drilling in the nearby area but nothing was ever confirmed. I seem to remember it popped up now and then in local newspapers. But again, nothing confirmed.
BP were operating in the local area at the time…
Slightly unrelated but the same speculated site, now operated be Perenco, had an oil leak quite recently into Poole harbour. I don’t know if that was fixed fast but the news came and went very quicky. Nobody talks about it now. Perhaps it wasn’t as bad as it was first thought. I don’t know.
