I'm in Mesa, AZ. The repeater I was referring to is the EAARS 145.21 (PL 141.3) 2 meter repeater on Jack's Peak just south of Silver City. It's linked to several in AZ, including one on Pinal Peak which I can hit from anywhere in the East Valley (aka eastern Phoenix Metro area). Not sure about the terrain between you and Jack's peak, but it's a pretty long haul from where you are...
There are also many repeaters that are linkable with VoIP using systems like Echolink, IRLP, and WIRES-II. I dont mess with them myself, but it is a way for two hams potentially anywhere on the planet to communicate with VHF or UHF, using the internet as the link between stations or repeaters.
Since you are new at this and may not understand how repeater linking works, the traditional system uses overland VHF, UHF, or microwave links to tie several repeaters together, which then basically act as one large repeater covering a lot of area. Most of these links are persistent, that is, the repeaters are always linked. Some are non-persistent and the link can be enabled or disabled by the ham using the repeater. Also, sometimes a mobile repeater will be linked in for special events. VoIP links use the internet, and are not usually persistent, i.e. they can be enabled and disabled by the ham using the repeater, and the user can choose what repeater (or station, node, etc. depending on the system) they connect to. It is also possible to do persistent VoIP connections between two or more repeaters, or to link them with other hard-wire communications technologies. It's all really cool stuff

Still, for talking over really long distance I think HF is way more fun.
