Successes with the John Glenn address?

[Spencerian35]

Way back in December of last year I sent a letter to John Glenn using this address:
John Glenn
c/o Ohio State University
304 Page Hall
1810 College Road
Columbus, OH 43210
USA
The letter was sent back over here a week or so later because it didn't have enough postage.So,soon afterward,I put the appropriate amount of postage on the envelope and re-sent it.It's now been over 8 months and I still haven't gotten a reply.Have you guys had any success with that address?
The guy is over 90 years old,and I respect him whether he replies or not(which evidently he's not going to do),but I thought he was a pretty willing signer,and it's really disappointing that I spent all that money on sending the letter apparently to no avail.
I'd very much appreciate any input you could give about the issue.Sorry for all my complaining.

I just got a success back today using the Ohio State University address. If you don't get one back, I would go ahead and resend.

Hi, just wondering when did you send the request?
