Smoking is fun and addictive!
Buy yourself a good thermometer so you can keep track of meat temp and smoker temp from anywhere. Very useful when smoking a pork butt overnight for example. You can monitor from bed. Maverick is a good brand but there are others.
Cherry is great for pork, I mix it with something other than fruit wood, like mesquite.
Twin packs of pork shoulder from Costco can feed an army for less than $30, and super easy.
I've moved onto the electric pellet smokers, the set it and forget it style is pretty nice.
Try reverse searing your next trip tip. I like mine med rare so I'll smoke it to about 100 to 105, and throw it on a 600+ degree grill to sear it until finished.
Just experiment and have fun!
