I can't give info specific to Clearwater FL, but many "semi-civilized" communities have at least a few "wireless hotspots" where connections might be made if the computer is equipped for it.

Borders and Barnes & Noble in most places I've been to recently have wireless hookups, although they do charge a modest fee (per connect, with a time limit) in my area. Rumor is that there's at least one McDonalds in my local area that lets you hook up for free, but I don't know if that's "policy" or just the local operator.

A fairly robust Federal Program has "wired" nearly all legitimate libraries in the US, and it should be fairly easy to drop in and log in - assuming she doesn't have overdue books back home. At libraries I've heard of, you have to use their machines, which may be maimed and crippled by local admin's rules, but reasonable browsing should be possible. It might be advisable to ask the Clearwater library before arriving, just to be sure they'll let her in the door.

My own local library is "extremely primitive," but I think that's partly due to a lack of skills on the part of some of the help. (They would check with her library back home to make sure she didn't have any unpaid late fees in the UK before letting her on.) Friends in one small Texas town (population about 300) seem to drop into their library and get access almost at will, or at least when the librarie's open, and firends' emails indicate they can barely read and certainly cain't spel. I'm not sure that either of the ones who use that library the most even has a library card.

Most truck stops have wireless hookups, but it's mostly a "trucker's only deal" - dedicated network(s). I'm not sure if she'd get on even if she rode into town in a 4-by, although she'd probably get a friendly reception.

Based entirely on rumors, she should absolutely avoid hotel hookups, as they can have lots of hidden - and very expensive - "extra costs."

You do need to check with your travel agent about restrictions on bringing computers in/out of the US, if that's part of your plan. There seems to be more difficulty taking one out (or back out) than bringing one in; but it may be necessary to get a separate visa for the machine (exaggerating? - maybe).

Is there a friend in the area who might have a hookup?
