Where can I take these damn kids today?

I’d felt competent in my role as the primary parent to a nearly 7 yo and 9 mo, but the holiday break and extra week being snowed in has exposed ALL the cracks in my game. I need a place to go today, with the kids, where I can get a bit of a break, or a shift in perspective, hell just a change of scenery may help us all like each other again… I’ve got a car and I’m not afraid to use it!

Any ideas? I’m open to anything that we can do at a reasonable cost. (Let’s set the max around $30)
