First clay shoot

[LordGrover]

Braces Clay Shoot tomorrow.

Apart from a stag do ten years ago, my first shoot. I'll be joining the complete beginners group tomorrow.
Any tips please? When I asked on the phone they said not to worry, just turn up but I don't want to turn up and make a chump of myself (per usual).
Given the weather forecast, I'll be wearing waterproofs and walking boots and maybe a baseball cap to keep rain off my face/eyes.
Would I be better wearing contact lenses or spectacles?

Any advice gratefully received.

Thanks chaps, all good advice. Really enjoyed it, though it was a bit windy and blustery! Probably hit 25 of the 50 clays on offer, not great but not bad.
Will definitely go again.
