It was so long ago that someone gave me the advice to bring earplugs to Mexico that I had forgotten all about it. However, yesterday while having lunch with a group of women, the topic of dogs barking in the night came up. I first asked if they had earplugs. I don't think anyone answered. Then I asked if they had the phone numbers for the owners of the dogs. No one did. I suggested that they get the numbers and call the neighbors at 2AM when the dog is barking. I have done that. It works. By the second time of telephoning them while you are awake, they never leave the dog out again.
I also never travel anywhere in Mexico without earplugs. The sounds one can hear if one does NOT have earplugs can be traffic, parties, fireworks, music, dogs, roosters (they do make their sounds all night), horses, cows, sheep and goats. The latter happened to me when I stayed near Patzcuaro in the country once and there was a farm next door on the lake. I had no idea animals such as cows, horses, etc. made so much noise at night. In went the earplugs.
On a planned trip to Veracruz City over the Christmas holidays, I was forewarned to be sure to bring earplugs. Good piece of advice. We were staying right on the jardin and the partying went on til about 4AM. I would have been very grumpy, if not for my earplugs. Many of the people I was traveling with were not so lucky.
Lots of people complain about the church bells that ring at least every hour, if not every fifteen minutes day and night, I think in San Miguel. Actually, I've been here so long that I don't hear or notice them. Well, I have to correct that statement. When sitting on the bench in front of the Parroquia, one cannot even hear, talk or anything else when the bells are ringing. Earplugs that close would not help.
The fireworks are the same thing. IF they are going to set them off, it is usually at 6AM. I might hear the first volley, but then I turn over and go back to sleep. I'm used to them, finally.
Therefore, when packing for a trip, I never leave home without my earplugs.........or my camera. Of course, they are readily available here in the house as well. You've been forewarned. Happy travels.
