[Rails] another select_list question - bad bad booleans

Probably because I understood drop down boxes (at least until this
issue) and hadn't bothered to do any checkboxes/radio buttons yet. - No
reason that I can't change my bad habits I guess.

It does sort of make sense to use a radio button since either is
required and I suppose I can default it one way for 'new' records.

Hmm...radio buttons...

Probably too late to tackle tonight as I am pretty much fried but even
with radio buttons, I will have to reverse the binary logic of stored
boolean back to common Yes/No vernacular.

Thanks

Craig
