Melissa,
Congrats on starting your RE journey. I wouldn't stress about the meeting. Think of it more so as a feel out to see if the agent is someone you would even want to do business with. Often times no matter what side of the fence you're on, it's an interview for you as much as it is for them. If they are a seasoned agent and investor friendly the 'meeting' won't be anything more than an introduction and getting to know your overall goals and criteria.
If you're planning to stop while passing through, I would look to setup a coffee somewhere and have a list of questions that would benefit you as you start your search in Montgomery. For example; which areas to look in for certain classes of homes, areas to avoid (due to safety or high crime), popular bars, shops, restaurants or universities, local market trends, returns expected in different areas etc. If you are not looking to pull the trigger in the immediate future I would pass on spending the day driving around with an agent and instead try to schedule a sit down with two or three agents that you've connected with prior (a quick local agent search and some reviews on each should help narrow the list). See how you vibe with each one and if their information is similar. After your last meeting I'd take some time and do a quick map search on the hot spots they mentioned and cruise through those on your way back home. Maybe even drive the not so hot areas just to familiarize yourself with the differences between the neighborhoods.
Best of luck, let us know how you make out!
Ryan
