That's actually my plan for this summer, if you can have a rerun plan without being a total dork. Some networks-mostly cable-do show new stuff over the summer. I think the 4400 comes back in June.
Said By Artemis PantharA good bet is to find a show you never/rarely watch and watch it over summer. It'll play reruns, but it won't bother you since you've never seen them before. Plus you find a new show to watch, which is always nice.
