I've been getting more practice (and been getting my husband to load the bike in and out of my SUV) and am getting the hang of it, still making adjustments to the seat angle and height, and learning how to balance well. Practice practice practice. Turns were an interesting learning experience, but am getting that too. Speed, especially on a slope, scares me a bit, but I finally figured out how to manage braking without stopping. Going up hill IS harder than I expected, but will get there.....
I'm definitely still thinking about the new bike, but trying to bloom where I'm planted for now, at least until I get the turning thing down better!
