the town over from us, La Plata, held a Fourth of July Watermelon Bash this year. it was free (including water, hotdogs & ice cream!) and had lots of water slide bounces, splash pads and even a fire truck spraying the kids! my kids had a BLAST! kullen really had a blast because his little bestie Richard was there!
they literally played and laughed ALL day long!
i hope they do it again next year! if you're local, it's definitely a fun-filled day for kids of all ages!
