Hey Teri,
Ben is correct, also spotter training or some of the other severe weather events (ChaserCon, etc) will sometimes help you find someone to chase with too.
Some advice though:
- I wouldn't just bring any random person wanting to go with. Most people don't realize what chasing is "really" like and sitting in a vehicle for long hours with someone you are unfamiliar with could cause issues (is the person annoying for example, etc). Also, some people literally freak out when they see a tornado (or they THINK they are seeing a tornado if they are inexperienced) so keep that in mind.
- I would make sure its agreed upon how expenses will be split up before you chase together. Some people are just looking for a free ride to see a tornado. I wouldn't let them do that (obviously).
- Another big thing to keep in mind is you "could" run into legal problems if something bad were to happen while chasing together. I'm not a lawyer so my advice stops there...just be aware it could be an issue.
- Are they going to be driving? I would make sure you know for sure they have a valid drivers license and insurance.
- What do they bring to the table? Have they chased at all or at least completed spotter training? I would make sure they are aware of their "role" for the day. You don't want to bring super-noob who suddenly thinks he's an expert and decides the best course of action is to punch the core of a storm when they have no clue what they are doing.
Anyhow, not trying to preach (just trying to be helpful). Good luck, hope you find someone in your area to chase with
