Eratosthenes Experiment: Know anyone in Alaska and Florida?

[O2HeN2]

This June 21st, on the Summer solstice I'd like to run the Eratosthenes experiment in three different locations, the Southern US, Colorado and Alaska.

I need to connect with folks in, say, Miami and Anchorage (South Texas would work too) and have them do the following at ~1pm their local time on Friday, June 21st (though the 20th or the 22nd would probably work just fine):

• On a flat surface setup a vertical stick - a carpenter's level (see picture below) would be perfect because it'd be an exact length AND allow you to assure it's vertical easily.
• About 1pm (I'll give them the exact time when I know where they area and which day they're taking the measurement) I'll need them to measure the length of the shadow cast by the vertical object on the [must be] flat surface supporting the stick.
• Email me their exact latitude, the height of the stick and the length of the shadow.

Anyone got some good buddies in either of those areas that can help me? Please PM me if so and I'll give you my email and phone number to forward onto them.

Thanks!
