One of the things I do to 'see' a country is go to a super market. Most countries have one row for chocolates / sweets. The Swiss have 3 rows. The French have one row for wine. Of course you have to 'adjust' the total size of the super markets to a 'standard' size. And they can change across the country. Ozie 'outback' stores have the bread in the freezer (supplies take longer than the expiry dates) and kangaroo tails are in the meat freezer... you don't find that in the Ozie city stores. Another common thing around the world is McDonald's... unfortunately. However even there, there are variations... and some use then as a cost comparison around the world - e.g. how much money/ or how much labour time does a big mac cost? On the wild/free camping .. yep, if they don't know you are there then you don't have a problem. I find where a road crosses a creek good due to the increased vegetation. Another place is on the inside of a road bend - the headlights don't go there as much. The alternative is camping where you are known, e.g. at the back of the Police station. Done that once. Noisy but safe? Bicycle riders camp more frequently than us, limited speed and energy, so this should help http://www.worldbiking.info/resources/free_accommodation_bike_touring_resources.html Finances. Look at your costs. You'll find the bike takes a good bit of it. Slowing down to say 50mph will substantially reduce that (both fuel and tyre). The next one may be food. And slowing down will increase that for the same distance (more stops). Don't starve but try to eat what the local 'peasants' eat... should be cheap and filling. While I'd not advise only eating this, I'd try to make it a regular part of the menu? Costs will also change from location to location, non touristy places can be cheaper, cities are cheap for food and tyres. The country is cheaper for camping... For Mexico try http://www.horizonsunlimited.com/hubb/bike-friendly-central-america-mexico/ for ideas of places. Depending on your level of spanish, doing a language course while doing a home stay in Mexico might be a good idea?
