Haha far from a pro but I’ve done it a few times! I’ve never done solo but it may be possible.
I think if I were to do solo I’d only have a predetermined zone I’d be willing to drive in—say staying in the front range of Colorado through central Kansas and bouncing around the zone depending on the severe wx outlook. During my trips I had at least one other person willing to drive, and we literally traveled thousands of miles each trip over the course of 7-10 days. One time we went from San Antonio to Corpus Christi to Amarillo in one day. That’s a lot to ask of one person.
Expect to spend between $100-150 each night for a decent hotel. Gas isn’t terrible if you have an efficient car. Rental car with insurance (and always get the full insurance in case of getting totaled by hail lol) isn’t awful as well but check around to get the cheapest price. Don’t forget to factor in food. Each of my trips cost at least $1k. Being in multiple cities alone is worth the cost IMO.
That’s all doable. The biggest challenge with a solo trip imo is the logistics when you’re actually in chase mode. Driving and tracking a supercell that could split, spawn a tornado, or throw out big hail far from the “center” sounds dicey.
If you did do it, I’d recommend keeping even greater distance and ALWAYS being prepared to move to a safer location. If you question in the slightest whether you’re safe, move immediately.
Other than that, hell of a thrill and amazing to travel the country. I’d try chasing again this year, but I think the tropics will have me busy this summer/fall.
