Grid issues.....

I was trying to move objects around late last night, and noticed the transformation jack wasn’t functioning. I resorted to numerically entering values in the location attributes to position things. This morning I realized the problem is the grid, somehow it’s gotten gigantic:( Anyone have any ideas how to change it back? I still have quite a few objects to place.

Never mind…stupid question. I must have accidentally changed the grid size to 10,000 in the viewport.
