Yes, this is a great thread!

Today I truly felt like I was in a hot yoga class as I was just dripping from every pore. It was raining lightly during much of the practice and so humid. For some reason I was really shaky today on all the one-legged stuff and even fell right down at one point (so embarrassing!) I have no idea why, but I was sweating so hard and really struggling with the heat, I guess.

Near the end when we were stretching, I turned towards the sliding door behind me on a twisting stretch, and there was a rainbow outside! The instructor saw it at the same moment I did and and said that there was an "arco iris" (the Spanish words for rainbow). It brought a smile to my face and ended the challenging practice on a great note.
