Constitutional Convention

If you had been a delegate to the Constitutional Convention, what would have been different?  Is there anything that you would have added to, kept out of or otherwise changed in the Constitution as it was written in 1787?

I realize that transportation may have been easier in the spring than it would have been in the fall or winter, but you would think that the men who had farms and plantations would have wanted to be home during the summer and fall, when agricultural work is most intense.  But for whatever reason the Convention sat during the summer, and by the time September came around the delegates were exhausted, both physically and mentally.  Major issues were brought up late in the Convention, but a majority of the delegates were in no mood to continue.  Just think how different the Constitution could have been if the Convention had met in the fall or winter when the delegates would not have had to fight the heat as well as each other.
