What a week we had in Barcelona, Europe’s Modernista architecural marvel. Followed by a train ride to and a few days in Madrid. The US really needs to embrace the low cost air carrier, regional airport, and train transportation options that Europe has. So many of the fellow travelers we met, who were from Europe, were in Barcelona on some ridiculously low airfare trip from London, Germany, etc. We are almost intentionally limiting social mobility and economic development by not opening up our transportation options.
