I spent about 7 min typing a response about attending a mosque and by the time I submitted it, the thread got locked.
Bottom line, you can freely attend any mosque without any issues, be aware of customs. Common sense applies here, how you would dress and act in church is similar to a mosque.
Walk in with a funny cartoon depicting prophet muhammed and you may end up with issues similar to if you walked in church with a photo chopped jesus tshirt of him and pam anderson on a boat.
I can prolly recommend a mosque within range of your area code if you like. PM me if it matters, if not have nice night regardless.
