I am a great believer in getting as much mileage from my tires as reasonably possible. I have also had good results with sticky string plugs. In your case, If you were on the road, I'd say "plug it and keep going" As you're at home, however, I suggest just replacing the tire. If you really want to mess with it, you might try injecting a small amount of rubber glue into the hole with a hypodermic needle. IMO, it's hardly worth the hassle for just a couple of thousand miles though.
