What can you do is the question ?

[Ketchn]

you could stop by a demolition on your way to work
you could ask if they would mind if you got some cinder blocks out of the pile as big as as a small town
you could load the bed of your truck up in less than 10 minutes
you could cut bamboo from the creek behind your house
you could even go so far as to bundle said bamboo
and tie it to a block
heck you might even find a spot it might hold crappie if you put it in the water
these are a list of things you CAN do to increase your chances of finding them next time out
is a boat and livescope and all the cool toys the ticket you might ask ?
SURE is my answer , but not all the folks that want to ketch crappie can afford that route
so keep in mind you CAN do it on the fly
not spend much money
and pitch a jig off the bank somewhere
and ketch crappie right easily and well on a limited budget
and yes KABOOM is the word btw
p.s. keep in mind only if its legal where you live and the added bonus is you are likely going to make some other person or persons day when they find it too
AND they (the crappie and the other anglers)will find it ....just saying
