Nice ride near Butte, MT

Dear Hugh,
Please don't feel that you need to respond to this note.
I know that my check reached you yesterday and I just wanted to give you a big thank you. I have rarely run into someone whose customer service skills can match up to yours.

I don't know if I will write a testimonial or not, but, if I do, it will be a good one.

I'm impressed with how this Catrike Expedition has held up. --JJ (13,000 miles)
