Help close a charity park

Stephens House and Garden need someone to assist with closing the park at 6pm. This will involve 20 minutes of work (with the park  gardener Josh) advising the public that the park is closing. Somebody local or if someone wants a one off mission to see a beautiful park in Barnet. Once the grounds of a wealthy Victorian family now held in trust for the people of Finchley. This a charity 'pocket park' (not council) and relies on volunteers and self generated income) Come to main house (opposite a zebra crossing Eastend Road N3) and ask for the Steward and he will give you the bell. You then just need to go around the park ringing the bell and telling people the closing time. You may not see the gardener. Please return the bell before 6pm. Max 2 people required. Why not arrive early and do a few laps around the park? Invite a GG friend to join you? Cafe and toilets on site.
