Being on the beach as the sun rises from the ocean is pretty cool. More than once I have felt like the molecules of light, the first ones at the first break of day seer right into my soul.
One of the coolest moments I ever experienced while tripping was during the day. A buddy and I did some acid on the mall in Washington DC. While walking in the wide open grass spaces around the Washington Monument, we sort of wandered into a huge flock of walking pigeons. Seemed that we were walking through a magical sea of synchronized birds...Amazing!
