I drew a tag in the Cabinet mountains at age 64. I hiked, I dieted, I hiked with weighted pack and acclimated to up to 8000’. I was in darn good shape. Altitude can be daunting and good gear is essential particularly good boots. First day was brutal, second worse, last successful. It can be a true mental challenge. Work hard, be in the best condition possible. Practice shooting up and down extreme grades. REMEMBER….each ounce equates to pain to pack. Prepare yourself for an incredible adventure. MTG
