One thing that probably goes with out saying ; Make sure you have back ups on any glasses or contacts you may use. Due to my weird allergies, I can not wear plastic/ acrylic lenses in my glasses(No contacts for me:( ) My lens fell out of my frame the other day and shattered. Went to the ophthalmologist to see if they could replace FAST as we are leaving for down South soon. I did have an old (5yr) pair that we hadn’t donated to the Lions yet. DH then took his old pair out and put it in his ditty bag for “just in case”. I also have hung on to ALL the appliances I’ve had over the years, crutches, leg braces, air casts, etc. I was a professional theater performer for 18+yrs and believe me sometimes ya goof up, twist an ankle, knee or get your foot stomped on(surgery). SO we kept all the stuff.If you have a place to store that stuff, I would keep it.
