I look at my beloved DF, already promised to my neice, and wish I could take it for a spin or two, but then I remember how high and out of control I would feel, how unaccustomed I've become to ever putting my feet on the ground, and how claustrophobic the DF makes me feel. Plus how hard it is for me to get ON it. So, though I will always enjoy looking at uprights, and even envy their riders a little, I'll just keep rollin' on on my trike.
