my hazy memory tells me Pic 1 & 3 is Mallory Hairpin with the white boards on inside, Pic 2 methinks is Creg ny Baa, I used to live up by Signpost don't recall ever seeing the road marked like that at Signpost, Pic 4 Ballaugh Bridge .... sorry - riders, bikes. outfits are a little before my "time" .. really good to see these fab pics and collective history, info, knowledge.
