1) DO visit Stax Records Museum. This place is amazing and has a plethora of information on the history and early days of soul music.
2) DO visit Graceland. The famous home of Elvis Presley. It is very interesting and has tons of information on the King of Rock n' Roll.
3) DO visit the Memphis Zoo! It's a really nice Zoo and has some great animal exhibits.
4) DO visit the Loraine Motel- the site of Dr. Martin Luther King's assassination. You can learn a lot, and even if you don't learn anything- it's a gigantic piece of history and worth seeing in person. DO prepare yourself for the overwhelming emotion that will build up inside of you as you approach the site. You may have to hold back a tear.
DON'T go in the pouring rain if you want to take pictures outside (and you will definitely want to)- DON'T let your husband try to take a picture with his phone as you drive by the Loraine Motel in the rain and almost run a stop sign and nearly cause an accident that could kill his wife and then blame it on you for freaking him out when you scream AAAHHH! so that he will pay attention and stop the car so you (the wife) don't die.
There's lots of DO's when visiting Memphis. Go to Beale Street, eat at B.B. King's, go somewhere and listen to some live blues music, ride the trolley, and buy a BIG ASS BEER on the street. (I didn't do that this trip, but I did it on an earlier trip to Memphis.)
With all the DO's in Memphis, try to remember a few more things not to do if you want your trip to run a little smoother. Don't step on your husband's big toe with your high heel when he's in his bare feet; it will hurt him. Don't be overly confident with your comforter on your hotel bed, if you tug hard and your hand slips off, you will punch yourself in the nose really hard. And if you must do that, don't do it while you're on the phone with the school counselor because you can't scream or cry until you hang up.
And last but not least, expect your kids to do the exact opposite of the list you left for them before you left town. Expect everyone to be late for school, get hit in the face with a soccer ball and almost break their nose, expect them to need way more gas money than you thought, expect them to melt the red solo cups sitting too close to the stove instead of drinking from them so they didn't have to dirty all the glasses, and definitely expect them to want more pizza.
Enjoy, Barrelassers :)
