So I have a separate 3rd car garage and decided to mount some overhead racks and clear out some space for a full-time optishot driving range. I added another 4 bulb fluorescent fixture to the ceiling and the place is really bright now.

I bought my mat (4' x 5') and net (9' x 15') from D.W. Quail Golf.  I LOVE that mat...highly recommend it.  Went in to Costco trying to buy a little 24" TV to mount and walked out with a 32" screen for a great price.  Does that ever happen to anyone else at Costco where you think you're gonna buy one thing and walk out with 5 others?  :-)  I hung the net with a little 1/2 PVC frame I rigged up and attached to eye bolts in the ceiling.    Also, for wall mounts for flat screens, go to www.monoprice.com for the best deals.  Great stuff.  I need to get one of those ball dispensers some other folks have posted.  Great idea!  All in all, I'm excited to go to the driving range after putting the kids to bed by walking out to my garage.
