RFO: The Night Sky Classes @ Robert Ferguson Observatory
Mar 27 @ 7:30 pm – 9:00 pm

The three seasonal series (six classes each) are designed for everyone from total beginners to experienced amateur observers. Whether you want to learn the constellations or have a telescope and want to expand your knowledge of viewing objects, these classes have something for you.
The focus is on learning the night sky in a “geographic” sense…locating yourself in our solar system, our Milky Way and our local galaxy cluster neighborhoods!
A few constellations are introduced in each class—their myths, history and interesting stars. We also cover deep sky objects such as the beautiful nebulae and clusters that never cease to awe and amaze.
After each class (sky conditions permitting), we go outside to locate the constellations just presented. We then move to the Observatory’s telescopes to view objects within the featured constellations, until or beyond 10:30 PM (11:30 PM daylight time).
Basic topics are repeated in each series so that concepts become familiar. Persons who take all three Night Sky series (18 classes in all) will learn the entire sky viewable from our northern latitude. (The winter sky is split between the Fall and Spring Series).
Series: $75
Single Session: $23 (available after first class of each series)
Camping: Discounted rate of $25 when attending these classes
Prices include admission to the State Park at class time.

Sugar-Hood Shuttle @ Sugarloaf Ridge State Park
Apr 8 @ 9:00 am – 12:30 pm

Want to do a through hike from Sugarloaf to Hood Mountain or vice versa?  Ride the Sugar-Hood Shuttle.
How it works
Every half hour our Shuttle will leave from either Sugarloaf Park or Hood Mountain Regional Park’s Pythian Road Parking Lot.  Make a reservation and then ride to the other end of the trail, or hike and ride back.   Riding first and hiking back to your car is the easiest way – no worries about how long you take to finish your adventure.
We recommend a reservation, but you can ride on a space available basis as well.
The hike should take 3.5 to 4.5 hours.
The distance is about 7.4 miles with approximately 2300 foot vertical climb.
Suggested donation of $10
