Greetings from Colorado!
I have to second the recommendation of Utah Trikes. Ashley and crew are great to work with.
I purchased my Trident Stowaway II from them last winter. I had a couple of concerns and Ashley at Utah Trikes and Tom at Trident Trikes stepped up to plate and really took care of me.

I like the fact that the trike folds in half and will fit into the trunk of a compact sedan. I drive vans [Astro and Windstar] and can the fit the trike ready to ride inside and still carry four passengers.
Unfortunately, I injured my leg about a month ago and it looks like I won't be riding [much less working!] for another 1 to 3 months...
SO! You guys enjoy the crisp fall rides for me!
