The holiest of all holidays, 420, is coming up sometime soon, but we couldn't tell you exactly in how many days. Some of us have been celebrating early — since last April 21, to be exact — so our sense of time is a bit warped. We did put our time to good use, however, by coming up with a list of things to do in Dallas, or wherever your strain takes you. 1. Imagine Ricardo Paniagua’s geometric mural in the West Village is a giant Magic Eye puzzle and try to find the hidden image. 2. Take a nap by snuggling up with the giant teddy bear statues in Lakeside Park.
