Best late April (spring break) bouldering.

I'm planning on taking a trip over my spring break (late April) to boulder elsewhere in the U.S. (WIsconsin may still be a little chilly and wet) and need some suggestions on places to go.

Some Criteria:
-I do Sport climb but the main focus is on Bouldering. I was thinking Red Rocks but I heard going there just for the bouldering would be a waste.
-I'm looking for somewhere scenic and somewhat secluded. I don't want to get to a greeat spot only to be greeted by 50 other climbers.
-Looking for rustic tent camping sites. Not the RV/Camper parks. A backwoods site (maybe requiring a permit?) would be good.
-I can make solid attempts on V4 but would like the majority of problems to be >V4 and would like enough to keep me busy.
-I have a week off and can fly just about anywhere in the U.S. I heard Hueco Tanks was nice but it may be a tad bit far away.

Thanks everyone!

Friends did Hueco for a spring break and loved every minute of it. Not that far away, similar to a trip to Red Rocks. Otherwise go down southeast and hit any of the Triple Crown bouldering series places that may be open for use.
