Groundhog day

Yesterday, I was watching the news on TV and they were talking about Groundhog day. I had heard about this day before but this year I decided to investigate a little bit to know more about this holiday in the United States and Canada on 2nd February.
There are several theories about its origin but where there is no doubt is about where is the largest celebration. This one takes place in Punxsutawney, Pennsylvania. It is a very popular tradition and now it is well-known in part because of a movie released in 1993 whose title was "Groundhog day" starring Bill Murray and Andie MacDowell.
The basic idea about this tradition depends on the behavior of a real groundhog called Punxsutawney Phil, the true weather forecaster if we believe its neighbors in Punxsutawney. Apparently, if the weather is cloudy when Phil goes out its burrow and it can't see its shadow, then it will go back to continue sleeping at home for at least six more week and that will be the time that winter-like weather will continue outside. On the contrary, if when Phil steps out his burrow the sun is shining in the sky (it can see its shadow on the ground) then winter is coming to an end soon.
I thought that we had strange ways to make weather forecasts using small rooster toys and saying that bad weather is coming when some body part is aching. However, I have changed my mind and now I think we are not strange people, we are just different. In my opinion, these traditions make TV weather forecasters more reliable and, believe me, I am not a big fan of them. Anyway, if you have a doubt, you can find a groundhog and ask it.
