Touring suggestions, any suggestions for biking . I am from SE Wisconsin looking for a warmer place that has good biking or trails that I can get to with Amtrack? Was thinking Southern Colorado. Something can rent for a week..

Gulf Coast, ? southern Colorado is still going to be cold, being high desert ..

Arizona and New Mexico becoming armed, Militarized, along the border,
will be unpleasant.

How about in your own backyard... a tour of the A&WS and, head up to the Canadian border?

Not a lot of information, but perhaps the Natchez Trace. You may have to do a round trip on the Trace back to Nashville to get back on Amtrak. Or, San Francisco to San Diego. Perhaps depending on how cold you are willing to tolerate, you could start further north.

I use to live in SE WI and was just telling friends about the Santa Rampage in Milwaukee. If you are around Milwaukee at that time, the Rampage is great fun.

Are you talking about now? You could probably still do the Katy Trail. Amtrak runs to both St Louis and Kansas City and another train runs between the two.

Amtrak also runs to Salt Lake City and a shuttle runs south (accepts boxed and unboxed bikes). That would make the Utah Cliffs Loop an option. You could also go to the Valley of Fire area and into Las Vegas. The same shuttle runs down to Vegas.

Also, the ACA Great Rivers and Underground Railroad routes run south from St Louis.

How long are you thinking? Just a week?

Phoenix. Word.

Warmer? Check!
Amtrak? Check!
Touring? Check! USBR90, Adventure Cycling Southern Tier, Adventure Cycling Gand Canyon Connector
Good biking and trails? Check! Bike lanes, bike paths and mountain bike trails out their ears.
Rent for a week? Check! Not sure if you want to rent a place to stay for a week, or rent a bike for a week, but either is available. The area has been infested with dockless bikeshare, as well.

Snark alert: so you're taking a two week vacation?

OK, with that off my chest, when are you looking to go? Now? January? Next summer? Lots of places are going to get even colder over the next couple months...

Unless you're going to hop a freight train, Tennessee's Amtrak connection is Memphis rather than Nashville.

Thanks for the responses. I am thinking of going in about a month, hence why looking for warmer. I don't like flying to much. I guess driving would be ok, if not to far, say 400 or so miles. The time frame on biking would be about a week or so. Renting a place for a while would be good. Or credit card tour bed and breakfast or the like. I am a bit older now, the last time I toured was quite a few years ago. , So something on the easier type of touring.
