It’s already August, so there are just a few weeks left to summer. No more lazy days by the pool or trips to the beach. But before you start feeling down, there is still time to have one last adventure before returning to the regular grind. If you’re on a budget, you don’t need to spend a ton of money on hotels or airline tickets. With gas prices the lowest they’ve been in years, you can have an epic journey with family or friends with a summer road trip.
