Observations about Bolivia mostly

Ok now we have been through:
La Paz
A Salar de Uyuni (and beyond) tour
Copacabana and Isla del Sol and Luna
Puno, Peru

Some things I have noticed:
- a lot of dogs have jackets.
- menus have either two choices (local spots) or 500 (tourist spots). Both can be good or bad.
- ATMs in Bolivia are great; they give you lots of small change. In Peru so far they are terrible because they all seem to charge a 5% fee.
- prices for big things (cars, etc) are listed in USD. This doesn't make sense to me; is it just to avoid the sticker shock of "7000 bolivianos" and "1000 USD" sounds better?
- altitude sickness can happen even after a week or more. It can make migraines even worse! It can also manifest in weird ways, like making small problems seem like big problems.
- Bolivia seems entirely cool and very low tourist hassle. I remember seeing some map saying that Bolivia was one of the most foreigner-unfriendly countries, and in our experience that couldn't be further from the truth. Peru (well, Puno so far at least) seems like there are annoyingly more hawkers and touts.
- I find it hard to enjoy things when there's even a moderate amount of discomfort. Like, kinda-wet socks level of discomfort. I think this is a major weakness in my character.
- bathrooms have been great. They usually cost 1 or 2 (or 5) bolivianos ($1=7 Bs) but they are pretty clean.
- Llamas have long banana-shaped ears. Alpacas have short stubby ears and are softer and really just overall cuter. Vicuñas look like deer.
