i hate guide servises, but i can see the need for them and yes i might use one someday, but it is a great way to fish new tecncs , water & fish.... i would just waste the hole trip at bass pro shop tappin on the fish tank, and looking @ lures i cant afford after 10minutes in the casino...LOL
did you post in the navada section? maybe just maybe someone will take you out, if you got the gas money and lunch it will help....
also look at boat rentals! lake mead is big but less than half the water holds fish! it's to deep! 8 hours on lake mead in july will be about all you will want to do with a guide or with out,unless you catch alot of fish~maybe... spf 50+ light weight long sleve shirts/ umbrella for shade, big hat & no beer till you git back to the A/C! dang i'm sweating already....
