not only am i excellent at not being very good at starting conversations with strangers, I'm a genius when it comes to failing to maintain the conversations strangers start with me... but i wouldn't let that completely put me off a few days solo touring. I'm happy enough with my own company.
I find that most conversations are beneficial, and you gain a lot of experiences, local knowledge and see sights you would miss but for these chats
It can also be quite fun, I once spent a fine evening with two charming young ladies after I commented in the pub that a local church had been closed and I had fancied seeing a particular green man. One of the young lady's Grandmother apparently held the keys, so off we went to unlock the church, I then got a guided tour and repaid the good turn by buying them a couple of drinks.
I have also been pointed to roadside memorials, detoured to churches , standing stones and burial chambers, camped in Alnwick Castle (pre Harry Potter), spent evenings with a couple of famous people, (and some less famous), been waylaid by rugby clubs, lifeboat crews, folk nights, and a thousand other experiences that make cycle touring what it is.
