Welcome from another short timer here. Hiking has an added benefit that far outweighs any other economic consideration- it's one of the most enjoyable ways to lose pounds without feeling like you are being forced to. It makes me want to eat foods that are of benefit to my health, not to my (much lessened) cravings for sweets and empty calories. As I quickly approach my 6th decade, my blood pressure, sugar and cholesterol remain at the numbers they were in my very active 20's. The beauty that you'll find on your hikes and the sense of adventure that's stimulated, will just be a huge added blessing. Enjoy .
