Wayne,
I was there 3 weeks ago for several days.
1. Road to racetrack was fine. Was slow in the 'van' we had, any kind of real 4WD would be fine. Looked recently graded to me.
2. No wildflowers to be seen at all. (At least we didn't see a single one that I recall)
3. Badwater had zero 'pattern's out on the salt. (none of the expected ridges). We walked out prob a good mile, didn't find anything.
4. Easy access up and around both Dante's and Aguerberry points. Can get right out to the end no problem.
5. Telescope peak still had snow then, no clue if still does sorry.
We had good cloud for the whole week, which was nice, sometimes too much in fact ! (didnt' get side light on the dunes when we were out on them for one morning).
Hope that helps !
Regards
Mark.
