The last 8 years I've lived in 3 different cities, all of them feature luxury gravel.
1. Minneapolis, MN. My home state.
pros- The Twin Cities is surrounded by prime gravel no matter what direction you head, all fast and smooth. Lot's of singletrack too. Quality of life is high. Excellent culture diversity, music scene is one of the best in the country.
cons- Winters are bad. You either get used to it, or never do and move again. Humid summers, lots of mosquitos and black flies. Even though the gravel roads are very good, it's all pretty much the same. Rolling farm grid.
2. Denver, CO. 2010-2015
pros-Probably the best access to gravel out of the 3, right from your front door. And more diverse. High Mountain gravel, b-road, and singletrack to the West, farm grid out on the Eastern plains. Surface conditions vary wildly. To some that might be a bad thing, not for me. There's even a huge gravel loop that cuts right through the middle of the city. Well more like a trail, Highline Canal. Something for any mood. 4 seasons like MN, but not so many sub-freezing days, so very ridable year-round. Quality of life is good. Getting better in the cultured dept as more people move there.
cons- Denver suffers from bouts of smog, inversion. It's easily avoidable though. Head to South to Castle Rock or Colorado Springs to escape it. Castlewood Canyon was my escape the smog loop. You have to become an expert in sun block and planning out hydration. Very hot Summers, it's high mountain desert after all. I got in a routine of starting rides an hour before sunset on the really hot days.
Portland, OR. 2015-present.
pros- Lots of gravel, and very diverse just like CO. You have the mountains and the farm grid. Best summers of the 3. Quality of life is high. Great music and food culture.
cons- Access to gravel from Portland is limited. All the good stuff is at least a 40min-1hr drive away. Only 2 seasons here, Spring and Summer. 7 months of rain, too much gloom. I've never had to take a vitamin D pill until I got here. Almost zero culture diversity. Trust fund kids and drug addicts everywhere. The politics in this state is extreme. Rural areas are full of really aggressive right wing kooks and white supremacists, cities are full of extremely liberal 20 somethings with too much or too little money. Every major city is overrun by homeless, trash everywhere. Hop on a trail and it's guaranteed you'll be bunny hopping over a sketcher impeding your way passed out with needle hanging out of them. I stopped counting after last year, it's pretty terrible.
Earlier this Winter I was posting on this forum about a similar move, with a strong desire to get out of Portland. I was looking at Bozeman, MT. and Hayward, WI. Both have everything I want in terms of cycling and other sports, except the culture part. Hayward is just way too remote. Well the place I was going to be at. 20 miles East, on a lake but 10 miles from the nearest town. Much has changed on my end since then. I'm going back to Denver sometime later this year. As it turns out I probably should've never left.
