I hate plaster.

Maybe not as much as birds, but I do hate it.  What's even worse is plaster under a leaking roof.  And we have both.  No problem, we'll just tear it out.  Did I mention that plaster is like brittle, dusty concrete?  So far we've removed the plaster from most of the kitchen (walls/ceiling), the master bedroom ceiling and the upstairs ceiling in the hallway/stairwell.  The benefits of this upstairs is we get to add recessed lights and insulation.  The benefits downstairs is a new kitchen.
