But, but what about this?
3. Two or more stamps in close proximity that are close enough to state borders to cross into two or more states and which you'd expect people to get in a single outing.

List the location from which trailhead you'd expect people to use to find the boxes. Ultimately, the location is where people drive to. The clue is where people walk to from wherever it is they park.

If you require someone to actually get back in the car to drive to a different trailhead for the next box in the series, it shouldn't be listed as a series--that would essentially count as two outings and should be listed as such.

Welcome to Maine, Ryan... why don't you pull up a tent and stay a while : )

So much to do, so much to do..... =) Maine is a beautiful state, though!

I hear theres a tiny gather in August that's just waiting to have you join : )

And everyone needs a Maine vacation... were cooking up lobster : )

Yep, Maine and Florida so that would be quite a drive from box to box! LOL!!

So basically we will plant the boxes as singles but in the clues we can mention "if you're in the area of XYZ look up the sister box to this" etc. Does that sound about right?

Check out "Anniversary Series" in my plants in my logbook. We plant a new one every year, in the location we visit for our wedding anniversary. So far there are 3 in Maine and 1 in NH.

Hi Maine Dane- I'm just reading through threads (and haven't finished this one yet); but my two cents on the mystery stamps is GOOGLE. And notes- when I think I've figured out where one is, I create a note, and add it to a map I created on Google Maps just to 'pin' the mystery stamps I think I 'found'.

In the box you could also put a note that there is a sister stamp in another state and give the name. Pretty much the same thing as putting the info in the clue, but more 'personal'. I like finding info and fun facts in the boxes :D

Hey Phazia! Thanks to you too for the input! I'm so glad I posted the original question because this has been very helpful. I've only got five boxes under my belt as plants so I'm still learning :)

I went to Florida a couple of weeks ago and we decided on our stamps. We each carved ours and she's planting hers this week. We decided to use the same name but we'll put our state at the end of the name of the box so it will a little different. And inside in the logbook we'll put the note that says something like "please check out the sister stamp in X titled ..." The worst thing that happens is no one makes the connection on the two boxes if they do find mine here in Maine and hers in Florida but we can live with that. I just want people to get out there and get boxing! LOL!! I'm still really surprised at how many people have never heard of the activity.
