elk in chester co.?

[BFit70]

i was over at my buddies house about a week and a half ago, and when i was leaving at around 1:30am, i heard what i could only describe as an elk bugle. heard it twice in about 30 seconds then it was gone. of course everyone thinks im loosing it (and i just may be ) but i heard something. what are the chances of an elk making it to chester county? i thought it could be someone screwing around with an elk call, but at 1:30 in the morning? what else could it have been? what else sounds close to an elk?

I hunt in Honeybrook and hear Elk Bugles all the time in the fall. Finally the landowner told me that a farm not too far from him has a few elk on the property that they raise, for what I don't know
