That's actually a really good idea (you could even play if it was raining). Several venues around the world have shade cloths or giant marquees covering some or all of their courts (e.g. Brisbane, Darwin, a couple that I've seen in Mexico), so the logistics of creating something similar in transparent plastic should be quite straightforward.I doubt it, grass courts are always outdoors, as they need sunlight. But surely Wimbledon could consider putting temporary bubbles over some of their outdoor courts so they could hold the tournament later on in the year?? That also means, they wouldn't need to offer refunds.
