Sorryif I'm misreading, but are you saying you can't use a crystal or glass call in the rain? That's the only friction calls that you can use in the rain. You won'tbe able to use a wooden striker in the rain, but you justswitch to an acrylic or carbon striker and call away. If you aren't able to use your glass or crystal call in the rain, you need to condition it more. I'd recommend using a stone to do it. I can take one of our pots with a crystal or glass surface,put some standing water on the surface, pull out an acrylic striker,and hit every note. That is a selling point of those surfaces vs. slate. That's also a good way to tell if your surface is ready for the woods. If there is water on it and the grooves are deep enough to grab the striker, you're good to go. That's why I prefer to carry crystal in the woods around here. It gets a little wet here in the Spring...among other times.
