Chicken Corners is one of my fav's, Monitor Merrimac trail, Newspaper Rock is another, and as has already been mentioned, take LOTS of water, I just got back from a Sand Hollow trip , temps 107ish, in 6 hours of solid crawling, I drank 8 24oz of water, and 6 poweraide electrolyte replacement drink and was still on the dehydrated side..
My riding partners felt the same, Another thing, those thin nylon sunshirts so popular with fishermen, a must have as sunscreen will quickly become abrasive sunscreen. The ones I have are made with thin hoods which are nice, especially if you don't have a roof..
Highly recommend a set of these if you don't have a flip up windshield, it gets hot fast
