National Tequila Day 
we all know tequila is synonymous with margarita, so let’s take a look at this frozen favourite.
There is no definitive answer as to who really invented this drink, but interesting stories abound. One of the earliest stories tells of a wealthy Dallas socialite inventing the drink at a Christmas party in Acapulco in 1948. Tommy Hilton of the Hilton Hotel chain reportedly attended the party, and took the recipe home to serve at his hotels. Another suggests that it is merely based on an American drink called the Daisy, which was made with brandy instead of tequila. The Spanish word for “Daisy” is “Margarita”; hence the name.

Cousins Day 
Remember those fun times at grandpa and grandma’s house when the whole family reunited and you spent countless hours playing with your cousins while the grownups discussed politics and mortgages? Many of us grew up around our cousins, spending summer and winter breaks with them and slowly walking into life together. Then came college and that amazing job opportunity out of state, and we gradually lost touch.

Drive-Thru Day encourages you to live on the wild side.
