Fishing This Week?

[impulse]

I'd like to do some fishing this weekend. Does anyone know if Bumsungran (sp?) is accessible and open?

As an alternate, I'd like to try some fly fishing. I have plenty of gear and just need a place. Without getting into any controversy, what spots would you recommend close enough to taxi from Bangkok (Asoke) and "cost effective". That means I can pay what it costs and I'm willing to pay more for a better experience, but I'd prefer to pay less if there are some good, less expensive spots. I do have a work permit if that's figured into the pricing like at BSR. Thanks in advance.
