My first resupply is going to be in Monson, ME. I was thinking that through New England I would like to do mail drops. Just wondering if anyone has ever....or knows if you can....drop a package off at the Monson P.O. rather than mail it there?? I will be driving through and this way I know it will get there on time. I mean I would expect to pay some kind of fee to hold it....or do you know of any places in Moson that you could do something similar??
