A few nice drinks recipe images I found:
The Rock Shandy
Image by pjah73
This picture stands alone, nestled in the middle of the trip for a reason. Winter or not, it got hot, and this, the Rock Shandy is without fail one of the most refreshing beverages I have ever drank.
Per the wikipedia entry "In South Africa, Zimbabwe, and Namibia, a rock shandy is made up of half lemonade, half sparkling water, and ice (usually with a few dashes of Angostura bitters)."
That entry does not do the bitters justice, it is no where near the same drink without it.
Angostura Bitters, most commonly recognized for it’s use in the Old Fashioned, is "is a concentrated bitters made of water, 45.6% alcohol, gentian root, and vegetable flavoring extracts. Made by House of Angostura in Trinidad and Tobago, the formula is a closely guarded secret, with only five people knowing the whole recipe.
Check out the wiki entry on it, you may recognize the bottle
