i am 63 yrs old and have acute chronic hip bursitis. i use a cane all the time. i live on social security. there is no way i can shovel my sidewalks. i have male neighbors on both sides of me, but they have no interest in helping me.every time it snows i get a note from my mail carrier that if i don't shovel the usps will stop delivering my mail. so i have to hire someone to shovel. this is very expensive. i realize that the carriers want clean sidewalks but when i have to hire someone to shovel i go without food. thanks usps!!!
