I think that is a very fine idea! In fact before you go visiting the Lodge, give the Secretary a call to let him know ahead of time.
First of all, welcome and I am sure that you can find something in Masonry that you are looking for that will be enjoyable. I agree with Bro. Stewart. Since you don't know of anyone you personally know being a Mason, going up to the Lodge on a meeting night would be the best idea. Getting a hold of the Lodge Secretary is also a great way to make sure that you have the right day and time to be there, and of course it will let the other Brothers there know that you are planning to come and meet them. Bro. Stewart gave you the URL to the Grand Lodges site where you can find some contact information and meeting information for the Lodge. However, I have seen that site be incorrect at times. So, another thing or two that you can try is to just stop by the Lodge and see if there are any phone numbers or names posted. I have had to do this a couple of times and luckily the Lodge had the Secretary and a couple of members' names and numbers posted. If they don't have anything posted, anytime you drive by and see a vehicle parked there, go ahead and stop in and ask for the Secretary's phone number and email address so that way you can get in contact with him. Anyone that is there and that is a Mason should be able to let you know the date and times of the meetings, but it is still best to get a hold of the Secretary.
One last thing. You can also come here and ask any questions that you have about joining and the membership. This site and forum has a great deal of VERY knowledgible Brothers that have spent a lot of time in Masonry and just as much researching and studying it. So, I am sure if you have any questions that can be answered, you can get it done by the Brothers on here.
Good luck with your search, and make sure you keep us posted on here if you choose to petition and when you will be initiated and all that!!
