Didn't visit yet Misiones (kind of a syndrom: once you live in a place, you say "oh well, now that I live here, I'll visit this place later" compared to some people I met who saw more places in 3 months in Argentina than me in 11 years, another subject that could make a nice thread).
Problems of heat & humidity could be solved (I don't use A/C/dehumidifier in my house or in my car, but I could) but still, it's indeed a handicap, and a big one (I just hate this hot & humid weather, not my stuff). Problem of choice, balancing the pros & cons (as usual).
Being close to BA: because I often buy Art & Antiques at auctions (I sometimes sell too, sold recently all my 19th century photos about Argentina / not all lots were mine though = was likely the biggest photographs auction ever in Argentina until now =

EDIT: + living near Bs As (or a really big city) is mandatory for me (like within a 2 hours drive from my home). For many reasons that can be easily explained.
