Death of the squat rack! recommended alternative exercises?

Thx to everyone for all the suggestions. I will try incorporating some of them into my leg workouts.

Went to the gym today and voila! the squat rack was back. It looks like the cleaned and repainted the rack.
leg workout today:

squat: 10 rep warmup, then 4 sets of squats.
walking lunges with two dumbells. 1 set of 10 (per leg)
leg curl machine: 10 reps
stretch
