Propose possible fixes for high goals

[ToddF]

So instead of just complaining about balls bouncing out of the high goals, let's work together as a community to solve this problem for FIRST. Does anyone have any proposals for how to solve this problem? Things to consider in your answer:
- effectiveness
- ease of installation and removal during field setup and teardown
- cost
- time to implement. If it can't be implemented by week 2 competitions, it doesn't help.
- aesthetics. Should blend in with the high tech look of the field and not look like something that was duct taped on at the last minute.

OK, go...
