MoraRach,
Would you mind sharing what a BBQ and America being a great country have in common?
I also think that America is the greatest country, even greater is the fact that my grandparents were accepted and given a chance here in the USA.
However doing something that Goyim do is not something that I would prefer. We spend the day together playing and having fun (like each Sunday) we daven and learn as well. Use this day of rest to cut myself off from work and enjoy life.
