Well our street is friendly, although there are some toerags living near enough who might realise we are doing ok and try to disrupt us.
But between us, we have at least 4 BBQs (2 on gas, 1 on charcoal/wood, 4th is a mini charcoal, and I suspect there are another few around as well) and some camping gas stoves etc as well.
2 of us have water butts off the gutters already.
Plenty of decent handyman/DIY skills (electrician, woodturning as a hobby, lots of different types of DIY jobs done successfully between all the men and some of the ladies!). Plenty of us not afraid to climb trees or ladders if need be (again - not necessarily the mens folk!).
Pretty skilled cooks, and well stocked larders and alcohol stores. As we include Greek background (who's parent, still living with them, went through bad times there), French, and grew up in Ireland in the 80s' backgrounds so used to frugality. 1 shed is a "man's shed" which is mainly devoted to beer (and a few tools). Couple of 2nd freezers in sheds. Couple of gardens growing veggies.
The only downfall is that, being summer (and after the end of winter was so bad!), we are all low on logs for the woodburning stoves and open fireplaces (and 1 open BBQ). But there are saws in sheds, and trees on the green that we can chop down.
Also, loads of bicycles to move people around, and to get to any shops that are open - and we tend to do things like shared grocery runs when bad weather etc hits (and then use the results to have shared BBQs on the green in the snow, with hot wine!). And a couple of people have cards for the cash and carry, so we'd do a massive group run first, and divvy out the proceeds of that to last us a few weeks.
And to avoid dealing with external factors, we would all (and not just 2) take out 1 fence panel between back gardens, and not need to go out the front door at all......
