I claim:
1. A portable net structure comprising:
- a net;
- a first pair of poles;
- a second pair of poles, each hollow and adapted for insertably receiving at least a portion of one of said first pair of poles;
- means for securing each of said first pair of poles in an inserted position within a corresponding pole of said second pair;
- means for securing each of said first pair of poles in a partially extended position within a corresponding pole of said second pair of poles;
- base means for supporting each of said second poles;
- ballast weight; and
- extended member coupled to said base means and extending outwardly away in general alignment with said net for receiving said ballast weight to secure said base means and poles against the tension exerted by said net;
