For all of you in the same boat as me, dry/hot weather-wise, I think I found a way of making it pour cats and dogs. All you need to do is to harvest your garlic and find a shady spot in which you place it to cure. Then, decide to air out your car, by leaving all of the windows open a crack, and promptly forget all about it. Then, just to make triple sure, hand-water all of your veggies by lugging back breaking buckets of water from the (only) distant water source. Voila! Instant deluge.
This method apparently works despite any assurances by all and sundry weather authorities of dry, hot weather for the foreseeable future. A gorgeous day with no humidity, and not a cloud in the sky will have absolutely no negative effect on this method.
Other variations of weather inducing activities can include, but are not limited to, hanging out laundry to dry, setting an outdoor table for an alfresco dinner, bringing out rugs/comforters/coats/etc to air out, hosting a garden party, or better yet an outdoor wedding, etc…
Please keep in mind that the more elaborate/expensive/easily water-damaged your activity, the bigger the downpour. Hope you have found this service announcement useful. Until next time; enjoy the weather.
