Hello. Friends and I are hoping to see the grounds at sunset in late March or early April. Sunset should be between 7:25 and 7:30 p.m. Does anyone know about how long into the tour we would stop touring inside the mansion and head outside to see the grounds? The main office/information team was unable to answer this question, so thanks for any tips -- including whether you wouldn't bother trying to time our tour to be outside at sunset!
