Grateful for my legs...however dumb they are!!

My legs are giving me fits. I have old lady knees; which translates to chondromalacia patella! The tendons that hold the patella in the right place aren't doing their job and my knee-cap rubs wrong. Anyway, it hurts. I have been going to physical therapy and they are better. I guess I should be happy. But this weekend is a hike with my family. I was supposed to go two weekends ago but I decided my knees needed the extra time. Well, here it is...hike time. Because of some of the exercises for my knees, my back hurts. So we are working on my knees AND now my back, too. And...I hurt. I'm scared of what I will feel like during the hike and after. I miss my years-ago hiking body that could do the Grand Canyon!! But, I am grateful for my legs. I can walk and if REALLY, REALLY pushed by something terrifying, I can run. I can take care of myself. I can do errands and shop. I can clean my house. I can play and help with my grandbabies. And, there are really great over-the-counter meds to help. And ice packs. But...I freakin' hurt and I don't like it one, little bit!!! But, I AM grateful for my legs! Here are a few pics from last years hike:
