Get ready for a battle of epic proportions on Sunday – and no, I’m not just talking about the “Game of Thrones” finale. Foundation 45 will be hosting the event behind Trees from 12p.m. – 6p.m. “featuring water balloon battles, water slides, dunk tanks, music, food and libations in the heart of Deep Ellum.” The only rules are you must be 18 or older and no pets allowed. General admission is $20 while VIP admission is $40.

Attend a block party this Friday night at Rex’s Seafood at the Dallas Farmer’s Market. Music will go from 6p.m. – 9p.m with an Oyster Happy Hour from 3p.m. – 7p.m. If you don’t have anyone to go with, you can join Dallas Critical Mass on its bike ride to the event. The cyclists will leave promptly at 8 p.m., so don’t be late.
