There is nothing like dropping lsd on a warm spring day. To feel the warm sun shining on you, is an amazing thing, almost like the sun is hugging you. To me, during the winter months, when everything is a colorless winter wasteland, night tripping is the way to go. But, going from day to night is cool too. My last lsd trip, was the week following this past christmas. We dropped the first hits around 1pm, and the second hits around 4. It's awesome, to watch how lighting and color shift, as the sun goes down. If you haven't tripped during the day, you need to try it, but it's best on a warm sunny day.
