Favorite thing: Oxford, OH is a college town with a very nice campus. The buildings are similar in design to give a 1800's feel to the entire area. Also, there is a lot a green space and you really feel at ease strolling through the campus. If you'd like a snack or more of a meal, there are plenty of restaraunts and snack shops around. Really a pleasant, fun place to spend a day.
Favorite thing: If you're in the area, you should head to Hueston Woods - a great park. They have rental boats, hiking trails, a lodge with a restaurant, cabins and camp grounds to enjoy. And yes, it is pet friendly. You might catch Oxford students practice rowing or RC boats in obstacle course competitions. A wholesome, fun place to spend the day.
