Isn't vinigar a natural disinfectant?  I believe that it is, that sounds like a good route.  I really don't want to go at all.  I haven't been able to figure out how to get out of it yet.  They might be happy w/ a party, but that probably isn't much better.  Tonight is Trick-or-Treat at the nursing home, No Way in H E Double hockey sticks am I bringing the kids.  There is usually a line down the street.  I wasn't able to convince them to wear a BioHazard suite as a costume.  Or astronaut.

Personally, just go buy candy and stuff it in their bag or basket.  I dont think they care where it came from as long as they get some.

Interestingly enough.....the clinic cancelled their annual "trick or treat" day.  I asked why....they said H1N1.
