4th Of July!

Today is the 4th of July. Like on my birthday I am still sick with he flu so we won't be going anywhere - not that I had anywhere to go. We do have steaks to BBQ and so that will give us some holiday spirit. One things that I don't understand today is why places around the country have the celebrations yesterday or tomorrow instead of today - the actual holiday? The town next to me is having their's on Saturday. I think the celebration of a holiday should occur on the actual day otherwise it is just a normal day.
