So you're going to the Historical Sites of the Church soon? 

HERE ARE A FEW TIPS!!!!!!!!! 

ONE. Go Humble and ready to be Spiritually FED. Each of those Missionaries have been set apart to help YOU come closer to Christ. They are not only there to tell you which shirt was Joseph Smith's favorite as you primarily thought! They are there after studying all morning, praying, prepping, filled with the Spirit!! DID YOU KNOW! That each tour is literally DIFFERENT?! Yes, that is because those Missionaries listen to what God wants you to know. If you go with the Spirit, you will feel it.

TWO. Ask a lot of questions! Participate! These tours are alll about YOU! Feel FREE to ask if the plates were made out of Led, or if the herbs hanging up are real! (They are not :() You can also ask them deeper questions like how Joseph Smith felt about his oldest Brother, Alvin, and how Joseph Smith's family was one of his biggest supports.

THREE. Have Fun! Feel the Spirit. It will be great.

Sorry, not much advice, but hear you me!!!! You will love it.
