Before heading into Laos last year, we stopped in Udon Thani, Thailand for two nights followed by two nights in Nong Khai, Thailand to chill out on the Mekong before crossing the river to enter Laos. This part of Thailand is off the beaten tourist path. There were tourists, for sure, but these towns are not on the top 10 list of hot destinations. This is a poorer part of Thailand that is dirtier and more polluted than I would have preferred. Nonetheless, the locals were all extremely friendly, the guesthouses were very clean, and the food was delicious.
Not sure which order the photos will be in, but I happened upon an audio shop in Udon Thani. The proprietor spoke 30 words of English and I spoke 10 words of Thai, so it was mostly an "Ooh, ahh" and "Thumbs up" discussion with plenty of smiling.
