Obtaining at early level
Getting the Intelligence bobblehead can be hazardous for an early level character due to large number of Super Mutants, Raiders, Centaurs, and Mirelurks in the area. Here are some known ways to get to this bobblehead with minimal risk:


 * Swim from the Anchorage Memorial all the way around to Rivet City. Take Rad-X and Rad-Away as needed. Alternatively, you can accumulate radiation and complete Moira Brown's Radiation Sickness portion of the Wasteland Survival Guide - just pop back to Megaton once you get the Rivet City map marker and get free Radiation healing from Moira as part of the reward.
 * At the Anchorage Memorial, use a Stealth Boy (see Stealth Boy article for locations) and run to Rivet City following the shore. This should get you 3/4 of the way there with your weapon holstered. Then sneak/run the rest hugging the shore to avoid the Super Mutant camp just West of the city. Activate the Stealth Boy as late as possible to maximize effectiveness.
 * Alternativly you can just run from Vault 101 to the northwest corner of the DC ruins and then down the pathway past Dukov's house. Keep running till you hit Rivet City.
