BEST: Udon has nice lake in the middle of the city, stuff to do around city (parks, lakes with water attractions, water parks, temples, budhas on the top of hills.....) and even a farang oriented night life.
WORST: Chiang Mai, full of broke hipsters that are "working" over the internet, that don't have money to buy a ticket to go back home, so they sitting all day with 160 Bath cup of cofee at free wifi, deciding which of 5 top most popular budhist tattoos they will get, so they can pull it out back in states when they gonna be giving speak about their spiritual awakening they found here.
