Well...... if you go to the member map and find my marker (in the Manchester area

.... even southerners ought to be able to find that!

)...... zoom in and go to satellite view...... the marker is placed on my Church. You'll see fields next to it.
I've used one of those fields before for a test firing. It might be possible to get permission to borrow one for a meet. But it'll depend on where the cattle are at the time. You'll also see the residential areas close by, so it's not an ideal location. But it is well connected for motorways and the Church has a lounge, kitchen and toilets (oh, and working heating.

).... and my whisky collection would be close at hand, too.
I'm not sure that it'd be suitable for a full on pyrofest because of the residential areas. But at the end of next September I'm looking to plan some events to celebrate some anniversaries - the 25th anniversary of my ordination, the 10 anniversary of me arriving as Vicar in that church and the 125th anniversary of the laying of the church's foundation stone. Good enough reasons for a few fireworks and maybe reasons that the neighbourhood would understand and tolerate fireworks for?
Mind you, I'm thinking there ought to be some better, less populated places that could be available. I've some in mind, but don't have any personal contacts with the relevant land owners, though..... well yet.
