Grammy might be joining us for a week and definitely will need something to get around - she has neuropathy and almost lost a toe this year. I think a scooter would work for her. Is that the same as an ECV? Can anyone recommend an offsite rental since I think that is the way to go. How do the rechargeable batteries work? Do they ever give out in the parks. I'm not worried about her learning to use it, she used to be a school bus driver - lol! Thanks for any help, I'm a novice at this.
