Which direction?

In Musselburgh today, checking on the progress of the new house, and glad to say it is looking good.

While getting some steps in at a local park, came across this huge concrete arrow, which upon further investigation is a directional arrow.

The arrow points towards the chilly waters of the Firth of Forth, where a series of targets were positioned in a bid to train pilots operating out of surrounding airfields like RAF Turnhouse (now Edinburgh Airport), RAF Drem and RAF East Fortune. Among the targets moored off the east coast are two midget submarines wrecks, which remain in Aberlady Bay today.

I love finding out and blipping local history.

Anyway, here's hoping you have had a good Saturday.
