See a pattern to this sequence?

[Creighton Dement]

Hello Seqfans, 

This seems like a possibly interesting, strange sequence of numbers. I
found the pattern: [odd, odd, odd, even, even, odd, even] but am
momentarily lost on how to proceed. I find no generating function using
Maple - at least not when passing it less than 180 terms. Does anyone
see other patterns embedded in the sequence before I submit it?

Sincerely, 
Creighton
