John:
I¡¯ll defer to Leslie, since there may be some time updates, but her presentation begins about 6pm and the observing will go until about 8pm. If it¡¯s in the parking lot at the library, as opposed to the field at the historical society, parking will be less than 50ft from observing areas. If it¡¯s in the historical society¡¯s lot, it could be any where from 20 to 100 ft depending on your choice of viewing spot.
