To me Sir Ranulph Fiennes said it best.
There's no such thing as bad weather, just inappropriate clothing.
I play all year round and I don't mind a bit of rain etc as the bad weather can add an extra element to games, eg reduced visibility or the rain covering noise. Just dress for the conditions.
I understand though if others would rather stay home when the weather is bad
Alternatively bad weather can be a good excuse to visit a cqb site if possible. Wht worry about the weather if you're indoors
