Again, not really sure why but everything seems to be working okay now. I
was messing around with it last night but when I went to sleep I was still
unable to connect. This morning I got it on my first try with the same
commands (I copy and pasted, so I'm sure they're the same). I'm still
stumped, but at least everything seems to be working. I'll still post the
commands just in case there's something obviously wrong that's causing it
to sometimes work and sometimes not.

aws ec2 run-instances --image-id ami-1a60f82a --count 1 --instance-type
t1.micro --security-group-ids devenv-sg --key-name devenv-key

aws ec2 describe-instances --instance-ids i-0fae36915f471378f --query

ssh -i devenv-key.pem ec2-user at

aws ec2 describe-security-groups returns:

SECURITYGROUPS  default VPC security group      sg-6703811f     default
120119680155    vpc-2ebb3449
