  We prove that the meandering set for $f_a(z)=e^z+a$ is homeomorphic to the
space of irrational numbers whenever $a$ belongs to the Fatou set of $f_a$.
This extends recent results by Vasiliki Evdoridou and Lasse Rempe. It implies
that the radial Julia set of $f_a$ has topological dimension zero for all
attracting and parabolic parameters, including all $a\in (-\infty,-1]$. Similar
results are obtained for Fatou's function $f(z)=z+1+e^{-z}$.
