Making it Rain
Certain subjects in nature can look even better when covered in dew or rain drops. In the Pacific Northwest, we get our fair share, but not always when you want it.
Ah, but there is an easy answer: you can create your own. A few pumps on a spray bottle filled with water will give you a nice dewy morning; a few more sprays will create raindrops. I use a small travel-sized aluminum spray bottle designed perfume. The fine mist spray works great and it's never leaked in my pack yet. Cost at a local store? $2.50.
Just don't overdo it or the individual drops will merge and everything will simply be wet.
