There's a chance that this is all over. I got home from hockey around 2 am and shone the flashlight under the picnic table and didn't see anything.
I'm going to check tomorrow morning and see if they are just somewhere else in the yard. I was going to do it tonight, but I was too scared to start wandering around, only to find out that they've moved over slightly and get attacked.
If they are gone I'll try to work with the pics I have, which is unfortunate because they're not the greatist (I'm also not a fan of the unflattering background of the pics, as we replaced some furniture recently and used that area to "dump" it until we actually "dump" it.
