We were unable to post your message?

Please excuse this post. I am unable to post the following message to
"Blew off my hatch" from Google Groups. I keep getting a "We were
unable to post your message". No other message or help. I tried to
post "testing please ignore" to the same thread and it worked fine. I
am wondering if there is some SPAM filter at work. So let's see if
this msg gets through via a new post.

$52? Here are some other sources for less expensive NACA ducts.
Black and Clear. These come with an intergral "exit" tube. Other
sources don't have this tube. Just google "naca duct".

Thanks.
