Hi Theresa,
Advice:
-wear sturdy shoes with good ankle support, the trail to the North Lookout is a little rugged
-take along something soft to sit on, nothing but rocks at the North Lookout
-take more clothing than you think you will need, it can get cold and windy quickly, think layers
-take plenty of water and snacks (stay away from soda unless you want to draw yellow-jackets)
-take your binoculars (obviously)
-wear a hat, you will be looking at an expansive blue sky this weekend
-bring along your painkiller of choice, looking up at a bright sky can give you a stiff neck or a headache
-the North Lookout typically is the best place to watch from
-if you are not well versed in raptor identification try to sit near the official counters as they will typically call out what they are seeing, or will be happy to answer questions about ID if you have any
-sit were you can see the "Owl Pole", we have been having a good flight of Sharpies, you may see some up close as they buzz the owl
You will need to pay the trail fee at the visitor center. The trail is across the road.
Saturday looks like it should be a good day NW to N winds.
I usually stay away from Hawk Mountain on the weekends due to the crowd but I understand, you have to go when you can.
There are other good hawk watches in Pennsylvania worth checking out. Look at their locations at this

I may get out to Waggoner's Gap Hawk Watch tomorrow, a good place for Golden Eagles, especially later in the season.
Good Luck,
Mike
