I haven't anything against the vaulted skulls, really- there are very valid arguments on both sides of the philosophy...but I know my luck, and a bird with a partially unprotected brain in my care is at a higher risk of something occurring, so I'm just being cautious. I do think I'll go count girls vs. boys with vaults, just out of curiosity, though!! Seriously, maybe leaving kids toys in the road will help! I'm just furious with these asshats that drive like that. It's sooooo bad. I knew a girl who had not one, but 2 major wrecks on gravel roads when we were growing up, with over 100 stitches in the face with each wreck- and it was due to speed on gravel with poor visibility. Perhaps when I hear her roaring down the road next time that lady will get a bouncy rubber ball in the vicinity, rolling down the drive. We don't have little kids in the area, but how the heck does that really make a difference? The speed limit on residential roads out there isn't 70, that's too sure!!
