keyboards are not biodegradable
you could kill a small animal if it decides to eat a key and choke on it. seriously, i know it was all in good fun, but clean up after you are done. you should adopt that stretch of road and clean it up.
those click-styles are by far the best keyboards IMO. i am typing on one now. sure i got my wireless one too, but nothing beats the feel and sound and just unecessary mass of the keyboard. gotta love them.
