When rushing to pack right before leaving it's important to remember everything you're going to need without adding a bunch of unnecessary weight and junk. This is especially important if you still travel like a college kid (in a small car with 3 to 4 other climbers). Whether your trip is meant to last a day or a fortnight, these lists have you covered. Itinerary, recommended locations, gear, and amenities all suggested.
Day Tripping - Can't get away for the whole weekend, but still want to get some outdoor climbing in?
Weekend Warriors - Arkansas, Illinois, and Oklahoma all make great getaways over the two-day weekend.
Cross Country - West, or East, go forth and seek adventure!
