Jan:
I did Whitney main trail day hike in June 2019 (lots of snow). It was a failed attempt. I came back in August 2022 and did same trail day hike and reached summit. I can share some information with you. Also, I am doing rim to rim in Oct this Oct and would like to ask you some questions. I can be reached at tpdeluca1@comcast.net if you would like to share information.
