We will be picnicking most lunches on our trip this summer, and I was wondering if it would be in bad form to have a bottle of wine if we were in a public park. On several of our picnics in France we had a couple glasses of wine with our lunch and it was lovely - so I'd love to recreate the experience, but not at the cost of breaking local laws. Unfortunately my googling has not brought me a good answer beyond that there are local ordinances. In the US it is the same, but 99% of those local ordinances seem to prohibit it. I didn't know if in England it was usually okay, or usually forbidden.
Should I leave the corkscrew out of our picnic set?
I know this is the England forum...but if anyone knows the rules in Wales and Scotland too, that would be great!
