It is amazing how busy the M5 motorway is. If you just stand at the GZ and watch for a while you can really appreciate just how busy!
Try and count the vehicles - it is really hard! I travel this motorway most weekdays so you might be waving to me at some point!
When I placed this I got two waves and I was not there for long! See how many waves you can get (or maybe even toots of the horn!) and let me know on your logs (if you want to!).
Should be a quick find - clip top box with room for swaps and TBS. My Geokids have filled the box with swaps to start it off.
