The folks I spoke with by phone last year in doing the research for where I was going to put in for...gave me an answer that 'caused me to look elsewhere than Hill Country for several reasons. Remember how bad the drought affected Central Texas. The lady informed me that they are/were going thru a major road project and were also updating other facilities to enhance their WMA experience over all, that she expected better access from the updated road system in the future would provide better harvest numbers.
That was last year about this time of the year, and I'd suggest a phone call followup in late August would give you better insight on the OP's concerns.
