Scott & I climbed at Alabama Hills over Thanksgiving ... Rumney-style bolting on Josh-style rock. Very loose rock, though. Seemed to be that most routes were north-facing, making it more of a summer destination than now. Worthwhile for a day, but a bit overrated - the g/b labels just about every route as ***, but you have to read the fine print (that the stars are only relative to AH, not 'overall'). But, you asked about bouldering ... sorry for the drift.
