Go to a farmer's market. Farmer's markets are adventurous because you never know what you're going to find. I love the idea of planning a dinner and only using things you find at the farmer's market.
Go on a road trip. Whether across town or across the country, when you're with the right people, road trips are just fun. Especially if you look up fun things to do along the way to your destination.
Spend an entire day going to places you've never been in your hometown. Whether you've lived in your hometown for a year or your whole life, I'm betting there are some hidden treasures you've yet to find. Spend a day exploring; going to all the places you keep meaning to visit but never seem to get around to actually going.
Visit the library. I say this a lot, but I will never understand people who do not take advantage of public libraries. FREE BOOKS. What else do you need to know?
Go on a picnic. Give me some cheap wine and some fancy cheese and a blanket and a field and I'm a happy girl.
Go thrifting. Give yourself a budget and then do your worst. If secondhand clothes aren't your thing, scout out furniture or fun home decor that can be revamped with a trip to the craft store.
What are some adventures your planning to go on this year?
