Taz....I would ask now...the worst they can tell you is "no", which isn't as bad as always wondering "what if"...good luck to you!

JustinL...you may be surprised....here in WV there was a plane crash recently (small plane, no injuries) that was caused by deer on the runway....send me your address and I'll mail it to you for some evidence to present to the O'hare people.... :-)
