@Boilingicicle, please do join us on the main Archers thread, or just lurk for a bit if that feels less daunting, although we are a welcoming bunch on the whole.
I've been listening for about 40 years actively, although I'd often been in the room when TA was on in earlier years (my Mum was an intermittent listener and liked to have R4 on when she was cooking, for company). I think you just have to plunge in and hope for the best.
Very briefly - they all live in a village called Ambridge, which is in Borsetshire, in the West Midlands. Nearest town is Borchester. County town/city is Felpersham.
Most of the people who speak have Archer blood or are/have been married to Archers. There are dozens of them. Ask if you can't work out who anyone is.
The pub is called The Bull and stands on the village green, where there's a duckpond and a children's playground. Opposite the green there's a community shop and post office. Nearby there's an ancient C of E church called St Stephen's. The village has a veterinary practice but no doctor or primary school these days.
Just outside the village there's a country house hotel called Grey Gables with a pool, health spa, country park and golf club. Nearby is the stately home of Lower Loxley, now run as a conference/wedding venue and tourist attraction.
There are several farms dotted round the outskirts of the village. Bridge Farm is smallish, organic and produces yoghourt, ice cream, cheese and vegetables. Also has a farm shop and a cafe. Home Farm is very large and has arable, deer and a fishing lake. Brookfield Farm is medium-sized and has dairy and beef cows, sheep, hens, some land used for growing wheat, barley and potatoes.
That'll do for now! Happy listening.
