I tried to buy just 1 LE and everything went through including transfer of funds on my paypal account, and I have recieved no error at all. But I went back and checked recent purchases on the account on their site and it is not listed.
So maybe I didn't get one? Who knows?
You would probably be safer with posting a note at a nearby cache and explain why you are doing it. "Notes" still track miles and don't effect your find count.
I thought it might be more also, so I ran it up through mapquest and sure enough it is about 400 miles and just under 7 hours one way.
If you are gonna make the trip, stop by one of our Meet and Greets they should be starting back up soon.
I know that at a few of the events here in maryland, when we have out of town guests the group usually tries to go hit the APE either the day before or the day after the event. But nothing as cool as an invasion.
