I take it that is Tewkesbury UK.
I live there and shoot with Cheltenham Archers, very good club, it has outdoor all year as well as indoor on 2 nights of the week. Have a look at the website for contact details. I wont be around on that date as I run a youth footie club and play on Saturday's. Outdoor shooting is at Cheltenham racecourse not too far away. Guests are allowed as long as they are with a club member.
PS I'd rather shoot than look round Tewkesbury.
