Ronnie Holbert signed in at Le Conte Lodge on Halloween of 2012 on his 62nd climb of Mount Le Conte. He wrote in the logbook, "I have missed this mountain." In a recent email, he repeated that sentiment and said he is eager to return to Le Conte once he recovers from knee surgery.
He knows it can be done. His friend Ed Wright (1925-2009) made the last 43 of his 1,310 Le Conte hikes after having double knee replacement in 2001—not to mention 132 climbs after heart bypass surgery in 1999.
