the unit below her is the same as the one she is on but for over 18's. this may range from two to 500 devices, with options in between. for the full list of ten, click here. would love to get hands on that guide as well. but a lot of people won't make the effort to plan ahead. i love that last night my team and i had a good time and lost to a great team. the bed is looking rather bare, especially with the annual azaleas dying off. :) fun experiment and love all the pictures.
