"Regionals and Some Observations Hunting Them When Traveling"

#PokemonGO: This is mostly based on my observations hunting a few regionals when I've been traveling. It won't go into the Lake Trio because anyone who can hunt them in the wild deserves heaps of praise (or is a spoofer).When we play locally, regionals can be a common nuisance. Tauros is pretty darn common for me. When we travel, things get pretty exciting and we try to pile up on collecting them.My first observation is that regionals either can appear in an area or they don't. It seems to be dependent on S12 cells (the Mr. Mime/Tropius line is the best observed). Regionals can overlap in a cell (Carnivine is in Tauros and Heracross territory) or have clear lines. There isn't a place that is "deeper" into the territory of the regional and spawns them more (however - some places are more favorable to that regional).Related to the disclaimer, the next observation is that regionals respond to biomes, weather, lures, incenses, and events. In the case of some events, regionals have almost entirely vanished. In general, Niantic has recently tried to avoid this from happening because it upset traveling folks. The current event is boosting Mr. Mime in Europe to what can be considered endemic levels.Corsola likes to hang around water areas, as do Tropius and Relincanth. Mr. Mime is found more often in more urban settings. Tauros is so common in my usual experience, that I never went on an expedition to find where they spawn. Volbeat/Illumise really pop up in the rain.I was hanging around the Tropius/Mr. Mime line a few weeks ago. The overall weather was sunny. I found myself quite a few Tropius, but very few Mr. Mime. This happened even with the ground event rolling around (providing an extra boost for the appearance of ground Pokemon). Last summer, when I was in a different part of Europe - where the weather and biome was more favorable, there were tons of Mr. Mime.I've heard of people going to New Zealand and hiking in the countryside who never catch a Relincanth. Another person did a business conference in Auckland and being constantly by the water was loaded with them.The easiest of any Pokemon to hunt is the first, when it's just an outline with the boosted range. Afterwards, you might have to put on your thinking cap and seek them out.Hunting regionals can be a bit of a challenge. You might be roaming on slower speeds (T-Mobile in the US offers free international data that is capped) or just using WiFi. If you can get a good data connection, you'll have a lot easier of a time. The more time you can spend with the app running, the more you'll see. Even running Pokemon Go Plus might nab you some Pokemon (but expect a good many to run away). Try and read up on where the Pokemon you're looking for spawns and remember to use your phone when you can maximize the odds.You're never guaranteed the Pokemon. RNG is RNG. However, you can boost your odds by playing in areas with more spawn points (areas of higher traffic cell use according to Niantic's outdated data). A very popular but very new attraction might actually spawn next to nothing, if the area was empty a few years ago. Rest areas on US roads seem to have a lot of Pokemon popping up. Going to high spawn areas is a chance to roll the dice more for the local regional - especially when the biome and weather match.Does anyone have any tips to what kind of areas seem to spawn specific regionals? via /r/TheSilphRoad http://bit.ly/30fqqlQ
