Solid idea. Having all the web sites like Ticket Master verify ages at time of purchase, and having stadium ushers check IDs. Sounds very practical. Much easier than putting up inexpensive safety nets.I think another angle to this story that has not been discussed is that many of these folks getting hurt seriously from foul balls are kids under the age of 5. MLB games are the most affordable of the 4 major pro sports and many parents bring their toddler aged kids to the ball park for their 1st pro sport experience. Back in the 1st half of the 20th century kids were never seen in a ballpark but since the '60s the age has gotten gradually younger to the point now that babies are actually being seen at the ball park. A 4 year old doesn't have the attention span to be awake for an entire game let alone the reflexes to be able to react to a blistering liner into the seats. Maybe there should be an age restriction for those sitting in the lower deck between the foul poles?
