FYI I've moved this thread to the USA regional area of the forum - where it might be more likely to find members in your area - but I left a link at the original location (Beginner area).
Yes, spearfishing is not everybody's cup-of-tea, that's for sure (although most seem to appreciate the fresh seafood it produces!

). Clubs are a great idea and can be lot fun and a source of friendship. However, living in a rural area, I learnt to spearfish from these DeeperBlue.com Spearfishing forums, and by spearfishing of course. While that might not be for everyone, with care and diligence and the helpful forum members, it is possible. DeeperBlue.com's forums are a great reference to search and a place to ask questions. I would suggest reading up on shallow water blackout (SWB) and look for calm, sheltered, fairly shallow conditions to start with. Be careful. The Spearfishing for Dummies, Speargun Rigging for Dummies, etc. guides on DeeperBlue.com - written by Miles - are excellent and have discussion forums associated with them

Len Jones Spearfishing booklet is also a good reference.
Another option, I suppose, would training courses (esp. for freediving) &/or paying to dive with professional guide. Or find one or two dive buddies.
