Does anyone know where building 15100 is? I'm more then sure it's on mainside but I don't know where exact. Thank you for the help! 

across from the air station next to mcdonalds 

awesome thank you! 

MCCS Human Resources? I ask because they are building 151100 and they are behind the Country Store. I went to the wrong Human Resources the first time I went to appy for a job! 

Any building starting with 15 is going to be mainside.

This will help you find it. 

DramaLlamasMomma is correct. The one across from the air station is not in 15 area. That's 22 area. The one you're looking for is behind the country store. I went to the wrong one the first time too. 

Yes, thank you I found out that the Human Resources I needed to go to is behind the Country store. But I thank everyone for all the help! Now I hope she gets the job.
