The Pennsylvania Farm Show is the largest free indoor agriculture exposition in the United States, and it features old fashioned entertainment at its best. Ever since 1917, farmers bring a plethora of cows, pigs, sheep, goats, chickens and ducks to Harrisburg every January for this crowded affair. The expo also features many vendors hawking everything from clothing and souvenirs, to food and drink products. The admission may be free but the parking isn’t. Rule of thumb; don’t wear nice shoes.
