I initially was going to use red but the Wife Unit pointed
out it was, like, rilly rilly ugly and would have none of it.
So I went with the white which is basically invisible during
the day.

I got it off'n ebay (search for "DOT Reflective Tape") but
it's available in various qualities (reflectivites) from
FLAPS, industrial supply places, trailer stores, etc.
