Buy some 2 gallon size zip lock bags for brining. Holds a single shoulder quite well and makes it easy to rotate the shoulder once a day.
After the smoke, let the shoulder rest for an hour then refrigerator overnight before thin slicing.
Get a seal-a-meal or food saver. One 8 pound shoulder will yield quite a bit of bacon and you really don't want to waste any, do you? Then freeze some!
Plan to be strong armed into a repeat cook by everyone who tastes the delicious product of your efforts. Friends and family can be very demanding...
Enjoy.
