User-script location

I’m attempting to add support for using Sublime Text and TextMate with files on the router: https://packagecontrol.io/packages/RemoteSubl.

Essentially, the script needs to be added to the /usr/local/bin directory:

curl -o /usr/local/bin/rmate https://raw.githubusercontent.com/aurora/rmate/master/rmate
sudo chmod +x /usr/local/bin/rmate

Unfortunately, the /usr/local/bin directory doesn’t exist (nor is it on the PATH):

# echo $PATH
/usr/bin:/usr/sbin:/bin:/sbin

Is there a recommended location for user-related scripts, such that they are on the PATH?
