We would like draw lines on the field, three rectangles 25 yards by 10 yards.  Also, we want to use the bathrooms and are willing to pay the fee associated with them.  I did not see the "Add Other Group" option so I just put the group as "Self".  Can I please get direction as to how to add a group? Thank you.
