Keep searching the archives. I learned a lot doing that over the past couple years. For example, in April 2003 I posted:

"I went north of Edmonds (yes, a couple miles past the cluster of pots right north of the Area 10 line). I set one pot at 230' and one at 250' at about 7:30 am and didn't make it back out until about 1:30 pm. Our first pull had a limit between the two pots."

AuntyM posted good advice:

"As far as where you're shrimping? Get a detailed chart on the depth and GPS coordinates, And you should be able to avoid ledges and drop offs. I use the online charts available at Maptech since my GPS doesn't have all bells and whistles. I print them out and take them with me."

In other words, keep reading, and once you have questions about what you've read, post a question - people seem to be happy to clarify what they've written previously.
