I took a very rare visit to Rye in April, and my luck paid off (at the expense of local passengers) across a shuttle bus operating on service 101, owing to gas works on the road between Fairlight and Pett Level.
I'd seen 36491 tracking without a service number at Rye earlier in the day and hadn't thought anything of it, and with the shuttle having only started the previous Friday (thanks Invicta...), it was quite a surprise to find it was doing 'something interesting'.
Commendably showing full destination blinds, it's captured here on Monday 17th April, leaving Rye Station on the last journey of the day to Winchelsea Beach via Fairlight Cove. Attempts at a second bite at the cherry the following morning were rather spoiled by my phone not picking up a 4G signal until I was too far up a hill to get back down in time before it departed!
