When it sporadically came online I was directed to my nearest walk in centre some 27 miles away (no surprises there)
Tiny 2 jab room set up & queues in excess of 4 hours (contrary to the 10-15 mins regaled over the phone)

Think ahead, umbrella, shooting stick, plenty of liquid, warm rainproof clothes snacks, downloads, maybe some loperamide& a sense of humour, yup it could be as protracted as my afternoon.
Overall time Inc travel 5 1/2 hours ..long day for the small amount of staff there (no let up) wife volunteered to go in & be a vaccinator on Wednesday & take some strain off the queue.
Good, patient, friendly, spaced queuing though, very civilised which helped no end.
I don't think I've spoken to so many people since lockdown 1.
Be prepared, it might get messy.
