Help Nonie Enjoy Her Garden Again

My dear friend Nonie needs help in order to purchase a portable oxygen concentrator. This will allow her to be mobile and get out more. She is currently confined to her home due to the size of the tank she has now, it is too heavy for her to carry. Nonie loves to garden, go for walks, and hang out at the JT. She hasn't been able to participate in all of the things she loves because she doesn't have a portable machine. We would be so, so grateful to anyone who is willing to help us achieve this for Nonie!! Many thanks in advance.
