On brutal days Saco Crag is nice as you can jump in the river almost every other climb (but they are short climbs)...May go without saying but wearing 50 SPF and climbing with a 100oz CamelBak with iced watered down Gatorade or equivalent can get me through just about anything...Cotton T-shirts are a must in the hot & humid as well... even the best synthetics ???feel??? warmer than thin cotton to
