HPHA Events HPHA EventsHPHA has a number of social, administrative, and fund-raising events throughout the year. Some of these are held periodically, some annually, some only once, and some in partnership with the Friends of Graeme Park, Greater Horsham Chamber of Commerce, or with other organizations.Most events, such as Margaret Strawbridge Daffodil Days, are open to the public and we would love to have you join us. Other events such as our Summer Barbecue and Corn Boil and Holiday Covered Dish Supper are a benefit of membership and are therefore invitation only. And others, such as our Para-Normal Investigations are open to everyone for a small charge.Follow us on Facebook or Twitter or subscribe to our newsletters to keep up with all events! xSummer Picnic 2012forget to take pictures until the picnic was almost over so only a few folks left.
