I have rheumatoid arthritis. I have been able to walk the parks, but was pretty miserable by the end of the day, and was sitting on benches when I could be looking around. I've been in a flare-up and believe it's time to rent a scooter. I have a few questions: 1) What outside companies do you all prefer? 2) Is it easy to recharge in the parks? 3) How about getting around in the shops? 4) Should I get a button that says, "Scooter Newbie"? (JK) I have used an ECV at Target and Walmart, so I have no problems using one. But those places have lower crowds. Thanks!
