The behavior of the conductivity σ, Hall angle tan θ, and thermopower 5 in La2-xSrxCuO4 for 0.03 < x < 0.10 is reported. Crossover to the low-T localized state, inferred from tan θ occurs at a temperature T0 that is comparable to Tcharge (inferred from NQR). The Peltier conductivity α = Sσ obtained from S also shows the crossover. We also briefly discuss the in-plane magnetoresistance in the low-doping regime.
