Mexican Yankee

Ingredients:

• 1.25 oz Lime juice
• 1.5 oz Tequilla
• .25 oz Maple syrup
• 1/2 bottle (6 oz) Ginger beer
• Ice (four cubes?)

Use a shaker to mix some ice, the lime juice, tequilla, and maple syrup. 
Do not shake the ginger beer! (duh)

Pour into a glass with more ice, and add the ginger beer.

Note:
The first version of this was 2.6 oz lime juice, 3.2 oz tequilla, .4 oz maple syrup, and a bottle of ginger beer.  Made two servings.  Adjust the proportions to taste.
