Do you want to spend some time this summer with this adorable kid?  We're looking for volunteers, 16 and older to help with goat walks with the kids, one on one.  You'll help with their training and supervise their grazing.  The average "shift' is about an hour and you can volunteer Tuesday - Saturday between 10 am and 4 pm.  It's a great way to earn community service hours or commune with nature away from the hustle and bustle of daily life.  Jack and the boys would love to make new human friends. 

Call Harriton House or email to: info @harritonhouse.org with the subject Goatscaping

Has the hot weather these last few days have you thinking about cool treats? You're not alone! 

Cool off at the all-you-can-eat ice cream extravaganza at Harriton House on Father's Day, Sunday, June 15th, from 1:00 to 4:00 pm. With the purchase of at least one regularly priced ticket, your dad or your favorite father-figure eats for free!

You'll enjoy premium farm fresh ice cream imported from Lancaster County. Why travel so far for ice cream you might wonder? One taste and you'll understand why. Our source for ice cream uses milk from an exclusively Golden Guernsey herd of cows, the same breed which was kept here at the Harriton Dairy. Between 1909 and 1927, the Harriton Dairy sold milk produced on the estate to local customers. 

Sure it's a long way to go for ice cream but we love the connection to Harriton's early 20th century history.

Reserve tickets at the link in our Linktree above or scan the QR code in this post. Both the link and code will take you to Harriton's Eventbrite listing where you can purchase tickets. When you reserve tickets ahead of time, you'll help save us from the embarrassment of running out of ice cream.
