Go check the "General" forum at NASGA. For about $20 at Home Depot, Orchard Supply or Lowe's you can easily assemble semi=permanent or easily removeable practice WOB standards that are adjustable up to about 16 feet. The stuff fits in a pickup bed, easy.

I'll be setting these up at our practice site at Stanford, for sure. If the Grounds guys take them out, I'm only "out" a few dollars.
