I would set out a salt block...gonna be fairly heavy though (40-50lbs) but will draw in the Deer,that and You could pack some mineral to pour out for the Deer also,that won't be as heavy and some only weigh in at around 5-8lbs dry weight.A Trophy Rock would also be a very good idea too,they are natural mineral rocks and they don't weigh a lot so it will draw the Deer in,provide minerals and last a good while.They also make smaller mineral blocks with apple flavoring etc...so one of those would help also.
