Greetings from El Portal. The Glacier Point Rd. is now open, but was closed due to the fire. The smoke in the Valley and El Portal is horrrendous. The Mariposa grove is supposed to open up again this fall after over two years of renovation. Hopefully we will get some cooler weather that will help with the fires. To get out of the smoke I spent my weekend up out of Tioga Pass where it was beautiful. I would suggest you check out Michael Fryes Photographers Guide to Yosemite. I hope this helps. You can always email me closer to the time you come. As a teacher, I dread another day of indoor recess because of the smoke. Still you might get some mysterious light.
