I always used to carry a chunk of 5/8" dowel. You can screw a mic clip onto it for plant mics. Paint it if necessary, fits in a C-stand knuckle, nail it up if you want. Cheap, light, and disposable. I also carried a putty knife mounted baby spud. Jam it in a crack in the set to mount a plant mic. Helicopter clip baby spud for dropped ceiling plants. And, of course, a knuckle to put on the baby spuds to hold the 5/8 dowel.

One odd thing that sometimes helps. I found that you can treat a spare windscreen foam with spray-on Scotchgard repellant. This will help the foam repel any water that falls on it without having any significant effect on the sound. Needs to be done ahead of time so that it can dry. The mic is a lot less likely to get wet. My experience with hogshair, also known as rubberized hair is that it very quickly becomes waterlogged. With heavy rain, it needs to be shaken out after each take or the water starts dripping through it. It does quiet down the sound of the rain and keeps it from directly hitting the mic and making awful noises. Obviously YMMV -- John Gilman
